Compared to the WH710/WH760 and Torque Dyno Specs
Let me start off by saying that I love the Seesii brand after watching Torque Test Channel's video on the original WH710 showing that it made MORE power than a Milwaukee M18 at the time. I've owned it for almost 4 years and it still runs like a champ and both batteries still hold a charge. The best thing about Seesii is that they use Makita style batteries so you will never not be able to find replacements if you ever need to, and if you have original Makita batteries they will work as well. I always wanted a "stubby" impact like the ones Dewalt and Milwaukee offer and this WH450 is the perfect size. Torque Test Channel also tested this Seesii Stubby on the Dyno and it made 227 ft lbs with the included battery and 247 ft lbs with a genuine 5ah Makita battery. For reference, the Milwaukee M18 compact made 249 ft lbs with it's best battery. That means this Seesii WH450 makes almost identical power at a fraction of the price! I included pictures comparing the WH450 with the newer WH760 and WH710 which are both mid torques. The WH450 is like a mini version of the WH760 which is really cool and something I really like. Weight wise it's MUCH lighter and easier to carry around and will make it easier to get in tough places. I used the WH450 to take off a steering wheel bolt on a F150 and removed a full size center console that is bolted to the frame with big bolts and it zipped everything off easily. The Stubby is super nice to have for jobs like that. Also ended up liking the 3/8 chuck since it has way more variety for smaller bolts while still having access to big sockets if needed. Seesii customer service is also top notch, had a concern with my impact and they went above and beyond to ensure I was happy. You really can't beat their tools and customer service for the price, especially since everything comes as a kit. Buy this while you can! They used to have a 1/2 Stubby that they discontinued and I regretted not buying until I snagged this one. Hope this helps! ... show more

Quality tool at a good price
Great priced high quality tool. I have used it only a few times but it had no problem removing bolts from water pumps that are used in harsh wet environments. High torque, durable and very nice balance.

Impressed
I am not using this for a job site or anything...just a regular home owner who does as much maintenance on my home and small engines as possible. This thing is powerful enough for that...easily removes lawn mower blade bolts and bolts from other assorted equipment. It's not particularly heavy or unwieldly and the battery seems to hold a charge sufficient for my needs. I would recommend to others looking for a similar alternative to the repetitive movement of a hand ratchet. ... show more

Great tool, It stood the test of time
I bought this tool to get some mechanical work on my truck, it git the job done, and I thought I would have it stored for a while. But you can use it as a impact drill if the need comes, just be advised, it's strong, you might end up breaking the screw/nut.

Great tool
Works great, able to remove lug nuts on my car. They were torqued to specs. Easily removed. Has a light setting for small jobs.

SEESII WH450 -ALL THE FACTS, and a little more.
5/23/2023- THE NITTY GRITTY: -Maximum fastening torque is 295 foot pounds, (400Nm). -Maximum nut-busting torque is 332 foot pounds (450Nm). -No-load speed in LOW= 0-2200 rpms, in HIGH= 0-2600 rpms. -Impacts per minute in LOW= 0-3000/min, in HIGH= 0-3500/min. -The price is right. Comparable HFT impact driver would cost $185. w/only 183ft. lbs of torque -3 year warranty and 24/7 email customer service. Very attentive. -Feels good and solid in the hand with a quality motor sound & feel. -Rubberized molded grip and also in blunt force areas. -Approximately 45º of free play in final gear at anvil. -Decent variable speed trigger feel, but not the best. -Choose Auto Stop Brake in reverse or normal reverse. Tool remembers which reverse mode last used. -Non-fan 2.0Amp charger is UL listed (not fake, I looked it up). -SeeSii's Amazon ad claims a 2 hour charge for the 4.0Ah battery (not tested yet). -Real time 4-segment LED manual battery meter on battery. Each LED fades as power is depleted. -The 21v 4.0 Ah battery has Overload, Overheat, and Over discharge protection. -No feet on battery or rubberized protection. -SeeSii battery model SE5000D. -Makita batteries may fit SeeSii. -Comes with 4 commonly used deep Impact sockets of ok quality. -Bright LED work at base, light is activated by trigger. Stays on 10 seconds after trigger is let go. -You can depress the trigger just enough so the tool comes out of sleep mode w/o motor activation. -English owner's manual is completely legible, however, it's a bit vague on battery care and feeding. -Decent blown-molded case. Tool, charger & battery fit tight. Sockets are loose in compartment. TIP: HAVING A TOUGH TIME GETTING SOCKETS ON AND OFF? Assuming there is nothing damaged with the anvil, hog ring or there aren't any burrs inside the socket, the best way to get sockets onto the anvil is to twist while pushing them on til they mate with the anvil, NOT push them straight on. Wiggle and pull the socket straight off to remove. Wiggling it helps sockets and anvils with machining anomalies (like metal burrs and clearance issues) clear each other during removal. It also help burrs smooth out. A little oil or light grease on the anvil may help to break it in but don't let dirt build up under the hog ring and periodically wipe the anvil and hog ring clean. This is only pertinent when first used. As you use the tool more and more, the anvil should loosen up. If it doesn't and you think the hog ring simply has too much sprung diameter, carefully try to squeeze it closed with the smoothest jawed pliers you have. DO NOT chew up the hog ring or anvil with vice grips. If you have any sockets that have burrs inside from machining, it's best to file them smooth or acquire better sockets. The sockets that come with it are okay for minor projects but cleaning up any poor machining and finish coating will make them EZ on-off. I did a lot of homework looking at sub compact cordless 3/8" impact wrenches / impact drivers, and I was just about to buy the Harbor Freight Tools Hercules new Model HCB81K1 Impact Driver kit for $97.99. The Hercules driver only has 183ft. lbs (2200 inch lbs) of torque UNFORTUNATELY, it turns out that the Hercules kit only gives you a tiny 2.0amp battery and the included charger "looks" identical to their 5 amp fast charger but is actually only a 1.5 amp slow charger. Oddly, they no longer sell either of these underwhelming item individually in the stores. They only come with the kits to give you a more perceived/deceived value (boo, hiss HFT!). If you wanted to get a decent Hercules 4.0Ah battery and 5 amp fast charger with their driver, it would cost you about $185.00 total and you'd still have the useless slow charger and low-tech under powered battery to dispose of (which BTW, small batteries DO inhibit the torque of the tool). COMPACT CORDLESS IMPACT WRENCH vs. AN IMPACT DRIVER? I'm actually surprised I have not heard anybody talk much about this, but in my opinion, I believe an impact wrench is best used for automotive repair and an impact driver is for woodworking and construction projects. Sure, either one can be turned into the other using adapters. If you plan to mostly work on your car, it makes more sense to get a compact impact WRENCH than a compact impact driver. With square drive, you simply attach your sockets which keeps the profile of the tool as small as possible. This is good for tight spaces. On the other hand, if you buy a compact impact DRIVER and want to use sockets, you'll need to use a hex to square drive adapter that will increase the length of the tool, making it harder to get into tight spaces under the hood. You can always turn an impact wrench into a driver with the plethora of adapters they sell on Amazon. So the question is, what will you primarily be using this tool for? I hope this helps.

Good enough for a full time professional.
It's great. It will remove a lug nut and I used it all day at work for a month before I charged the battery. Just bought their mini chainsaw and and the long electric ratchet and impressed with all of it.
