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. Guitartec

Ok better when broken in
I work as an auto mechanic and figured I would try this 3/8 impact I took it to work used a few times seemed a little weak SEESII customer service contacted me and asked me what was wrong, and they decided to help me out with a stronger impact wrench and let me tell you they did just that they have some great customer service the kit I received not only is strong but its good enough to use at work. Used it all day and battery life is great, I recommend you buy this if you need a cordless impact wrench

Great tool with very good performance for the price.
Well,In the limited time of use with this tool so far, I'm pretty darn happy with it. I'm sure I've not put it to the test of max it can do and battery longevity and all that, not even close. But what I have asked of it, it's done very admirably. I'd recommend it in a heartbeat for your basic DIY type with home projects.

2nd battery
I have been using my 3/8 impact for awhile now. I gotta say it's awesome. Battery last for really Long time! I am avle to retire my snapon,makita, and mac 3/8 electric impact tools now! But I'm trying to buy another 2nd battery for my seesii 3/8 impact but can't find it anywhere. That's why the 4 stars

Compact and powerful.
I am not a mechanic, but there are things I do know how to do. Recently it became time to put on new brakes and whoever the person was before me must have used a cheater pipe hooked to an aircraft carrier to tighten the bolts. I absolutely could not get them off and almost knocked the car off the jack stands in the process. But this little tool...zipped them right off! It is small enough to get it where I need it, and powerful enough to do what I want it to. I just wish I could order an extra battery for it.. but when the time comes for a new one, I will just rebuild this one.. As for the included sockets, I have not used them. I ordered a set separate from this impact gun. But the gun, battery, charger case and overall quality I could not be happier with the product. Very solid and comparable to the expensive stuff.

Brim outlook on quality control and longevity.
The media could not be loaded. I bought my 3/8 Seesii impact wrench January 2024, through amazon. I have not had the opportunity to use it yet, but today was the day I was going to. As I took it out of the box and put a fresh battery in(Have 2 other Seesii tools, the small chainsaw and a 1/2 Impact. As I hit the trigger, Item was dead on arrival. the item makes a weird noise and doesn’t turn. Tried multiple batteries, all buttons combinations and nothing works. Getting a hold of customer service has been a hassle so the warranty that is being offered is also quite inconvenient to put to use.All in all, my experience with Seesii has not been great. I am now second guessing my purchase of the 1/2 Impact and the chainsaw, which have also seem very little use. Will they also last 1-6 months? I hope Seesii or amazon will help potential customers with this issue and make it right.
