Super good stuff

So I've needed a good cordless 1/2" impact in my arsenal for awhile now. However I'm "frugal" and didn't want to drop the coin on one. Well, I finally got tired of trying to use cheater bars in confined spaces, or trying to secure an item while I bust stuff loose. Besides, I'm getting old, I'll leave that for the young fella'. So I started doing research, as I knew in this day and age there had to be a knock off(s) alternative for a garage wrench monkey, that wasn't going to run me a couple hundred for the impact, battery & charger.So off to YT & Google I went. This was getting decent enough reviews for my liking and it had a coupon as well, so I rolled the dice. It works great for my needs. Breaks lug nuts off no issues, then again I don't hammer them on with an impact, nor do I break out a 6' cheater bar when I tighten them. It made quick work of pulling pinion & carrier bearings with a clamshell puller tool. Its busted every nut I've put it on. While I don't use it on a daily basis, it has seen plenty of hard work since I bought it. I'd highly suggest this to anyone that wrenches on their own stuff in the garage.

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.

Amazing tool. Did not expect it to be this strong and amazing. You don't need a compressor anymore. This tool does the job even better than anything I have used.

Power per dollar can't be beat on this unit. I ended up buying 2 of these, one for the shop, and one to keep in my truck as a traveling impact. "Larger-medium duty" : Handles lug nuts and suspension bolts with ease. Reasonably compact in size/weight but it might be a wee bit bulky for smaller disassembly tasks. I consider it a Medium size impact which "hits above its weight". Unlike its predecessor/sibling, this one has a "soft start" where it ramps up the torque (to a higher peak torque than the sibling). I kinda like that when I assemble parts because not every bolt needs max torque.
