    Gets super hot when under pressure my old dewalt out performs this thing by far thought I would give it a fighting chance but after about a month or so this thing is trash

    I purchased this for a large home project where I had to drive 1500 or so screws of various sizes. The compact size of the tool is nice for getting into tight spaces, like between wall studs with longer screws. My smaller 2 amp existing DeWalt batteries lasted for hours. I purchased this model because of the brushless motor design, as it’s supposed to get much better battery life. I think it really works because the batteries really lasted a long time. The speed control has great control too, so I could set the screws perfectly even for delicate work. I was driving a lot of #9 3 1/8″ screws for building framing, and it would drive those screws as deep as I wanted and fast with very little twisting on my wrist, and then if things weren’t quite right, unscrew quickly to start over. I also used it for small #8 1 1/4 screws for trimming and it worked wonderfully there too. I used it on some very large screws in a couple cases, #12 or something, and it worked great there too. Like any impact driver, the impact makes quite a bit of noise when you’re driving large and long screws. I was working close to small farm animals in tight quarters a few times and had to avoid the impact to keep them calm. Could be an issue with neighbors too if they live too close, like in the next apartment.

    This product claims to have more power than previous models, however it doesn’t have half as much power as my old dewalt driver. I’m very disappointed in the decline of dewalt tools I’ve always been a dewalt guy but it might be time for a change… This was a huge waste of money in my opinion.
