. Overall it's decent for the price, which is quite cheap. Hey, a good set of 60 gauge drill bits is about $100. So if you want a great set for precision work, shell out another $70. However, I use the smaller #50-#60 mainly for drilling in wood. I don't try to drill into metals and don't expect them to be good at it. For what I needed to do, they are just perfect. If I needed a kit for more precise work on metal etc I would put C on the best kit. You can't spend $33 and expect a $120 set. except #54 which wobbled very little. But as soon as he hit the tree, he apparently stopped. That too is $33.
