The included sockets are spread out too far, with a 3mm gap separating the larger sizes. Our car's lug nuts were too large for the included 21mm and too small for the 24mm, so I had to use one of my other sockets.The sockets mount using a ring rather than a bearing, and in practice, this makes it much harder to get the sockets on and off. There is an odd magic moment when they suddenly come off after pulling and twisting in every imaginable way.While the impact wrench feels well-made, its effectiveness seems highly dependent on the compressed air source. We used a 3/4 HP compressor that maxes out at 100 psi, and when setting it to the prescribed 90 psi, the impact wrench struggled to remove the lugs. However, this is likely due to the shortcomings of the compressor. After an attempt, I'd have to wait a few seconds for the compressor to fully repressurize before trying again. Eventually, it worked, sometimes. The attached video should give you an idea.Despite the quirks, the wrench remains useful and speeds up a tire rotation, but I wouldn't trust it to secure the lug nuts without a follow-up hand tightening.
