Seesii WH700 Impact Wrench Review: budget high-torque gun that’s stronger than it looks (but not 650 Nm)

I picked up the Seesii WH700 because I was tired of cracking lug nuts by hand twice a year for tire swaps. I didn’t feel like dropping big money on Milwaukee or DeWalt for something I use a few times a month at most, so this one caught my eye: two batteries, a case, sockets, bits, and a torque figure that looks pretty heroic on paper. I went in expecting a noisy toy, to be honest.

After a few weekends of use on my car, some random bolts around the house, and a couple of stubborn fasteners on a small trailer, I have a pretty clear idea of what this thing can and can’t do. It’s not a pro-grade tool, and the 650 Nm number is more marketing than reality, but it’s also not junk. It sits in that middle spot: way better than a basic no-name special, but not at the level of the big brands.

In day-to-day use, it does the main job most people will buy it for: taking off properly torqued wheel nuts and speeding up basic wrenching. Where it starts to show limits is on over-torqued or rusted hardware, and in the general feel of the plastics and the controls. You feel the price difference compared to the premium brands, but you also feel the savings in your wallet.

If you’re expecting a magic tool that will break every seized bolt on an old truck, you’ll be disappointed. If you just want something cordless that gets car wheels off, helps with DIY, and doesn’t cost as much as the vehicle you’re working on, this Seesii is actually pretty decent. Just go in with realistic expectations, not the spec sheet dreams.

Looking at the price versus what you get, the Seesii WH700 lands firmly in the good value for home users category. Two batteries, a charger, sockets, bits, a case, and a brushless impact wrench that can actually remove properly torqued wheels – that’s not bad at all for the cost. If you only need an impact a handful of times per year, dropping double or triple the price on a premium brand just doesn’t make sense for everyone.

Where the value drops a bit is if you go in expecting pro-level power and durability because of the advertised 650 Nm. In that context, it’s disappointing. The real torque is clearly lower, and the feel of the tool reminds you that this is a budget option. There are also mid-range brands that sit between this and the big names, which might make more sense if you wrench a lot but still don’t want to pay top dollar.

For someone like me, who mainly uses it for tire swaps, some brake work, and the occasional DIY project, the price-to-performance ratio is pretty solid. I don’t need Bluetooth, fancy modes, or a tool that survives a construction site war. I just need something that speeds up jobs and saves my arms. This does that, even if it’s a bit rough around the edges.

If you’re on a tight budget or just starting to build up your tool kit, this Seesii kit makes sense. If you already own a battery system from a big brand, I’d probably stick with that ecosystem instead of adding another charger and batteries. But purely as a stand-alone purchase, the value is hard to argue with, as long as you ignore the marketing hype and see it for what it is: a decent, budget-friendly impact for light to moderate use.

Design-wise, the Seesii WH700 looks like most generic cordless impact wrenches: chunky head, 1/2" anvil, blue and black plastic housing. It’s not pretty or ugly; it’s just a tool. The weight is around 3.5 kg (about 7.7 lbs) with battery, which you definitely feel if you’re holding it up for a while. For occasional use on wheels or bolts at waist height, the weight is manageable. If you’re under a car or working overhead, your arm will start complaining pretty fast.

The handle shape is decent. The rubber overmold gives enough grip, even with slightly oily hands. The trigger is reasonably progressive: squeeze a bit and it starts slow, squeeze more and it ramps up. It’s not as smooth or precise as the big brands, but you can still feather it enough to avoid instantly hammering a small bolt to death. The LED work light is basic but useful when you’re in a dim garage or under the car.

Where the design falls short is the forward/reverse switch. Other users mentioned it and I agree: it’s badly thought out. The markings aren’t clear, and the switch is long and a bit loose, so you can easily bump it and change direction without noticing. The first time I used it, I also ended up tightening instead of loosening a lug nut because I misread the direction. Once you know this, you double-check before pulling the trigger, but it’s still a weak point in the design.

The overall build doesn’t feel like it’s going to fall apart instantly, but you also don’t get that solid, tight feel you get from Milwaukee or DeWalt. There’s a bit of flex in the plastic and the finish is more “good enough” than impressive. For home use, it’s acceptable. For daily pro use, I’d be worried about long-term wear on the switch and outer shell more than the motor itself.

The dual battery setup is honestly one of the main reasons this kit makes sense. You get two 4.0 Ah lithium-ion batteries, and even if some people suspect they’re closer to 2–2.5 Ah in reality, the run time is still decent for home use. I managed a full tire swap (all four wheels off and on), plus some random screws and a couple of bolts on a small project, all on one battery, and the indicator still showed full. How accurate that indicator is, I can’t say, but I never ran out mid-job.

The charger is basic but works. It’s not a super fast charger like on premium systems, but for a DIY user, it’s fine. You can charge one battery while using the other, which basically means you never really run out unless you’re doing continuous heavy work. For most people changing tires, doing brakes, or some light construction tasks, one battery per session is more than enough.

What I like is that the brushless motor helps with efficiency. Compared to older brushed tools I’ve used, this one doesn’t heat up as fast and the battery doesn’t feel like it’s draining in minutes. After a solid 20–30 minutes of on-and-off use, the tool was warm but not roasting, and the battery still had juice. For occasional weekend use, that’s totally acceptable.

The downside is that these batteries are tied to Seesii’s ecosystem. If you already own Milwaukee, Makita, or DeWalt, this doesn’t slot into your existing chargers and packs. Also, long-term durability of the packs is a question mark. They work well now, but I haven’t had them for years, and cheaper packs sometimes fade faster. Still, given the price and the fact you get two, the battery situation is one of the clear positives of this kit.

Durability is where you really feel the difference between this Seesii and the big-brand guns. The motor being brushless is a plus; that usually means fewer wear parts and better long-term reliability on the inside. The outside, though, is where corners are clearly cut. The plastic housing has a slightly hollow feel, and the seams aren’t perfectly snug. It doesn’t feel like it’s going to crumble in your hand, but it also doesn’t give that “I can drop this off a truck” confidence.

I’ve used it on concrete floors, knocked it over a few times, and tossed it back in the case without babying it. So far, nothing has cracked, and the anvil still feels tight with no noticeable play. The included sockets haven’t shattered either, which is usually the first sign of cheap accessories. But I wouldn’t call this a jobsite tank. If you’re a mechanic using it every day, in and out of cars, getting covered in oil and abuse, I doubt it will age as well as Milwaukee or DeWalt.

The weak point long-term will probably be the direction switch and plastics. The switch already feels vague out of the box, and vague switches rarely get better with age. If something is going to fail first, my money would be on that or the battery contacts if they get knocked around a lot. The batteries clip in fine at the moment and don’t wobble too much, but again, it’s not the tightest fit I’ve seen.

For a home user doing a few jobs a month, I think it will hold up for several years if you’re not throwing it off ladders. For a pro who uses an impact all day, every day, this is more of a backup or emergency tool than a main gun. It’s durable enough for casual use; it’s not built for constant punishment.

The big selling point on the listing is the 650 Nm / 479 ft-lbs torque claim. Let’s be blunt: it doesn’t feel like that. If it truly had that much torque, it would be in the same league as heavy-duty pro guns, and it’s not. In practice, it’s strong enough for most home jobs, but the numbers on the box are clearly optimistic. I’d put it closer to the 100–150 ft-lb range based on how it behaves on lug nuts and how much extra tightening I can still do with a torque wrench.

I tested it on car wheels torqued to about 100 ft-lbs. It removed all the lug nuts without drama when they were correctly torqued and not rusted solid. When I reinstalled them using the Seesii and then checked with a torque wrench, most of them still needed a bit of extra twist to hit the proper 100 ft-lbs. That lines up with what one Amazon reviewer said: it’s more of a “gets it close and speeds things up” tool than a precise final torque solution. For most DIY jobs, that’s fine as long as you always finish with a torque wrench.

On tougher stuff, like older suspension bolts or slightly rusted fasteners on a trailer, it’s hit or miss. Some bolts came off after a few seconds of hammering; others needed penetrating oil and then a breaker bar. If you’re dealing with heavily corroded hardware or stuff that’s been air-gunned on by a shop, don’t expect miracles. It helps, but it’s not a magic rust breaker.

The variable speed and two impact settings (0–2600 and 0–3300 IPM) are handy. For smaller bolts or when using it as a drill/driver, the lower speed keeps you from instantly stripping stuff. For wheels and larger bolts, the high setting does the job. Noise-wise, it’s loud like any impact gun, but not worse than others I’ve used. Overall, the performance is good for casual users, just don’t buy into the full torque claim.

The first thing that stands out with the Seesii WH700 is how much stuff they cram into the box. You don’t just get the impact wrench and walk away; there’s a whole starter kit. Inside the plastic case you get: the wrench itself, two 4.0 Ah 21V batteries, a charger, six impact sockets (17–22 mm), a bunch of drill bits and screwdriver bits, a strap, some rubber rings, and a basic manual. For a home user who doesn’t own much gear yet, it’s basically plug-and-play.

In practice, I mainly used the included sockets for wheel nuts and some suspension bolts. They’re not premium, but they fit fine and haven’t cracked so far. The drill bits and screwdriver bits are more of a bonus. I tried a few for light work like drilling into wood and tightening some furniture screws, and they worked, but I wouldn’t rely on these bits for heavy, repeated work. They feel like the typical “thrown in for value” accessories, not something you’d buy separately.

The case is fairly compact and keeps everything together, which I like. It’s not the toughest case in the world; the plastic flexes a bit and the latches don’t feel bulletproof, but for throwing in the trunk or storing in a garage, it’s fine. I wouldn’t use it as a step stool or toss it around a jobsite and expect it to survive for years, though.

Overall, the kit makes sense for the target buyer: someone who wants a ready-to-use solution. You don’t need to run to the store for sockets or a battery. Just charge it and go. If you already own a pile of better sockets and bits, you’ll probably ignore half the accessories, but the two-battery setup at this price is the real interesting part of the package.
