I am an audio visual professional who often deals with small Phoenix style connectors. These are small flathead screw terminal Euro blocks. This product works perfectly for those types of connectors. It also works well with the hex head.
I was originally concerned about an electronic screwdriver bud. The fact that the motor can lock and you can rotate if you need to get extra. Torque is perfect.
The level of variety of heads for this screwdriver is also extremely impressive. The non-battery version that comes with the kit is made of high quality aluminum. There are also a plethora of other useful tools for small areas such as precision tweezers and a really nice metal pry bar that is very thin.
Overall, I am extremely pleased with this purchase. So far. The battery life seems to be pretty good but you can never really tell until you put a lot of use to the product. I will update.
Don't purchase this product Expecting the torque of a handheld Milwaukee drill. This is a precision instrument that you can use to get extra torque manually by hand, but it is not meant to replace a drill.
If you go into this purchase with that mindset you will be incredibly impressed with what you get for the money!
