ok

I bought this torque screwdriver to accurately torque some M6 aluminum bolts. Yes, aluminum bolts. (only Porsche would dare do this...) Yes, it does what it says it will do. It will torque any fastener that needs very low torque input relative to the torque wrenches most of us have in our tool box. The directions are ok at best and could use a lot more explanation of how to reset to a different torque setting once a setting has been set. I dialed my torque setting into the wrench per the instructions and then went about torquing 13 M6 aluminum fasteners in a 2-step procedure. The first thing I noticed is the screwdriver has no ratchet. So as you torque a bolt, the screen that shows the torque may or may not be facing you. Mostly, not facing you. You can't just back a ratchet mechanism up and twist since there is no ratchet. But, it does have visual LED's (that you can't see when facing away) and an audible beeping to let you know how close you are to the set torque levels. I did learn that even without being able to see the readout hearing the beeps did work fine. I would prefer to both hear and see as I approach the torque setting. Now, I'm a big person but I have to tell you twisting the 1.5"-2" diameter handle to 30 inch-lbs to 40 inch-lbs is not easy. You really need more mechanical leverage to easily control the torque as you approach the desired setting. A torque screwdriver designed for really low torque levels needs some sort of T-handle type design to help slowly and controllably approach the torque setting. The small diameter just doesn't have enough reasonable leverage. When I went on to the second stage of torquing the aluminum bolts I tried to increase the torque setting. I thought I'd just keep pushing the up arrow and that would be that. Unfortunately, that didn't work. I looked at the directions and found no help. I turned off the torque wrench and then turned it back on and it then let me increase the desired torque setting to the second step. So, overall, not great but it did what I needed. I don't know if there is anything better out there or not. Hopefully this will help you decide what makes sense for you.

Works great

For scope and rings

Works great and great deal

First of all, this is not an electric screwdriver. It’s a digital display that allows u to adjust the torque specs but u must manually turn it.I was/am looking for an electric screwdriver that allows me to adjust the torque specs for my Rc cars and trucks, but does the screw driving for me. If u feel like having to manhandle your screws and small bolts to a specific torque setting than this mat be for you. If you are looking for an electric screw driver or drill driver that allows u to specify torque THIS IS NOT THE ONE.

I have been testing for a couple of weeks or so, and it seems to work fine, but the quality of the material isn’t good enough, in particular where you have to insert the tools, is very soft and feel very delicate.
