This is my first time using and owning a impact gun. I have no knowledge of impact gun to compare this. Everything about this Seesii looks and feels like quality. I used it today 03/29/25 to change all the wheels on my vehicle it made that a easy task. I attempted to torque the lug nuts more manually and couldn't. I allowed my neighbor to use it to remove his wheels with ease. The battery indicator was still showing three bars from battery out of the box. So far I think I made a GREAT purchase.

I was very surprised this tool is amazing it out worked some of my others with ease for the money it’s a great tool

Had it for about a month now and surprised how well it works and how easy it takes rusted nuts and bolts off upside not to heavy

This is basically an apples to oranges non-professional review of the SeeSii WH750 Flagship model 1/2" compact impact wrench and the Seesii WH450 3/8" SUB compact impact wrench. This review will be updated when I use the WH750.2 weeks ago, I purchased the smaller SeeSii WH450 3/8" compact impact wrench, which I just returned the other day for this larger, more powerful SeeSii WH750 version with much more than twice the claimed torque of the WH450, but a little bigger in size. In fact, this more powerful version has torque specs and features that are up there with all the physically larger and heavier pro versions of Milwaukee, Dewalt, Makita, Kobalt, Rigid and Hercules at a fraction of the cost. It's literally more tool than I'll ever need for my purposes.The smaller 3/8" WH450 was strong enough for my automotive repair needs and is an excellent value however, its 3/8" square drive would only fit my standard sockets, not my impact sockets, which are all 1/2". This would've caused me to use a 3/8 female - 1/2 male" adaptor just to use my impact sockets, thus making the smaller wrench physically longer and making it harder to get the wrench in tight places.-WH450 has 2 forward speeds & 330ft. lbs (450Nm) of breakaway torque up to 3000rpms, length of 5.11" (129.79MM)-WH750 has 3 forward speeds & 738ft. lbs (1000Nm) of breakaway torque, up to 2400rpms, length 6.69" (169.93MM)Both models have auto stop brake in reverse and normal reverse modes, an LED work light at the base of the handle. The WH450 comes with a 21V 4.0Ah Li Ion battery and the WH750 comes with a 21V 5.0Ah Li Ion battery. When checked with a multi meter, these batteries are actually 20V batteries. Both can use Makita and other Chinese impact wrench batteries.FACTOIDS:-The square drive chuck has a compression ring which is supposed to keep the sockets from coming off, however you may need to widen the compression ring a bit depending on your sockets. It's ok if they are a bit tight to install on the chuck as they will eventually loosen. If the sockets don't stay on, you may need to physically spread the compression ring with a small flathead screwdriver (don't over do it and break it).The proper way to install a socket is to twist the socket on until it lines up with the square drive as you push it onto the chuck. DO NOT JUST PUSH THE SOCKET STRAIGHT ONTO THE CHUCK. For socket removal, wiggle it straight off. Due to the tooling, this will get easier as the tool ages.-I asked The Torque Test Channel on YT to test this 1/2" flagship model against other top models in it's class. It did surprisingly well against all the top tiers and even surprised the channel's owner.- SeeSii is pronounced "CC". I checked with the company.

I bought this impact wrench kit to store in my car trunk as an emergency tool in case I get a flat tire. It's overkill for that purpose, but it's a nice tool, and the price was right with the coupon, so I bought it.The tool and battery are compatible with Makita's battery platform. To be safe, I wouldn't charge the SeeSii battery with a Makita charger. I would only charge the SeeSii battery with the SeeSii charger included in the kit. Nor would I put a SeeSii battery in genuine Makita tools. However, putting a Makita battery on this SeeSii impact wrench should be safe.The Amazon listing states it includes a 4.0 Ah battery, but the kit I received has a 5.0 Ah battery.With the 5.0 Ah battery, the tool and the battery weigh 5.7 lbs. The bare tool itself weighs 4.4 lbs.The torque specs: maximum tightening torque is 627 ft-lbs. The maximum loosening torque is about 738 ft-lbs.I've only used this wrench to loosen lug nuts so far. Be careful when using this impact wrench because it's very powerful. I encountered one cross-threaded wheel stud while loosening lug nuts on my Toyota Corolla. As I used this impact gun to remove that cross-threaded lug nut aggressively, the wheel stud snapped. Had I used a breaker bar instead, I might have been able to loosen the cross-threaded stud without breaking it.The only thing I don't like about this impact wrench is that the hog ring (or friction ring) doesn't produce a tight friction fit with sockets. It only takes a very SLIGHT finger force to pull a socket off. As the hog ring becomes worn with use, I am concerned that the friction fit will be even less secure.The 1/2" drive chuck is a hybrid between a hog ring design and a detent pin design. It comes with a friction ring, but it's not a pure friction ring design because the nipple has a hole in it to allow a steel pin to be inserted into it. It's also not a pure detent pin design because it doesn't have a spring-loaded ball permanently built into the drive chuck. Instead, the drive chuck has a hollow hole through which a steel pin can be inserted to lock a socket securely in place. The pin is then held in place with a rubber o-ring placed on the socket. The kit comes with two steel pins and two rubber O-rings. I only see this hybrid drive chuck design on Chinese-made impact wrenches.The chuck is sorely lacking as a friction ring design because it doesn't provide a secure fit with sockets. When I used this impact wrench to remove tire lug nuts, the socket repeatedly came off the 1/2" chuck due to impact vibrations. The only way to keep the sockets from coming off would be to treat the chuck as a detent pin design. Unfortunately, it's not a true detent pin design. There's no detent ball permanently built in. To secure a socket to the chuck, I first have to put a socket on the chuck, insert an included pin through the socket and into the chuck, and finally secure the pin with an O-ring around the socket. This process would make the chuck function as a quasi-detent pin design. I would have to do this process with every use and every change of the socket. That removable pin and rubber O-ring will both easily get lost. The kit comes with two pins. Seecii could have prevented much hassle by building the chuck as an actual detent pin design from the get-go. To summarize, the hybrid friction ring/detent pin design is neither a well-built friction ring design (because it's too loose) nor a true detent pin design. Instead, the hybrid design on this Seecii impact wrench captures the worst attributes of both.
