All the tools included are strong and feel good in your hand. I only charged the drill once when I first got it two months ago and have been using it almost every day since then without charging. Not heavily used, just a few screws or holes drilled here and there, but still pretty good. However, there are two things; The first is a bag. I wish it had some little pockets for bits, sockets etc. That's all lost there, especially since I've added a few more everyday essentials than I'm sure. most others do too. The second problem I encountered was the bit strength. I drilled a 5/32 hole in soft wood and it just snapped. It can only be bad materials and not an everyday occurrence. By the way, this was the first time I used this nozzle. Overall, the cost and durability of (most) the included tools outweighs any small downsides I had with the set. I would for sure buy again.
