Made in China. For what it's worth, it's probably fine for some people. I have a Kingsdun Y0 size three point bit set to replace the trackpad in my old 2008 Macbook. I found that the Chinese-made Y0 triangular screwdriver had so much play when inserted into the screw head that I decided not to use it due to the risk of tearing off the screw head. If that happens then I'm going to have real distance issues. The Y0 size screw is small, so removing the screw head is a real problem. Basically you have a chance to get the distance right. Consequently, I bought a German-made iFixit Y0 three-point screwdriver for about $9 plus shipping, and it fit snugly, allowing me to loosen the trackpad screws without damaging the screw head. Basically you get what you pay for. I couldn't find a German made Y0 3 point screwdriver on the Revain website. If you don't need small bits, you'll probably be happy with the Kingsdun kit for around $18.
