13 Pre-set Torque Screwdriver Keys with S2 Drill Bits, 0.6 cm Torque Wrench Set for Maintenance, Tools, Repair and Assembly of Bicycles, Torque Range from 10 to 70

Excellent for what it is, definitely not for heavy-duty use, but I use it for optic mounting and it's perfect for that. Comes with a nice enough box. The dial/torque selector could be a little more accurate or rather easier to read, but it's to be expected from a product in this price range, and I'm still overall very satisfied.

It does the job. I needed it to torque a rifle scope. It was easy to use and did the job. I cross referenced it with my buddy's more premium torque wrench and the foot pounds were accurate. It comes in a nice, durable case and I don't expect to need to replace it anytime soon.

If you’re installing optics or doing your own gunsmithing, this torque screwdriver is a must-have. Proper torque is critical for mounting red dots correctly, and this tool makes it easy to achieve consistent, repeatable results. I verified its accuracy using a calibrated torque measuring device, and it was spot on throughout the range I tested. The build quality feels solid, the adjustments are easy to make, and it’s simple to use. Whether you’re mounting optics, accessories, or other firearm components, this is a tool I highly recommend. It’s a great investment for anyone who likes to work on their own firearms.

I have a torque wrench that I use, but needed something that worked like a screwdriver (since the socket type approach doesn't work well in Circuit Breaker panels, etc. I just need to drive some screws. Also, I needed inch-pounds which my torque wrench doesn't support. I got some screws and compared them. After comparing, they both agreed at the same torque, so I am quite happy.

Seems like a solidly made tool. I have not verified how durable the bits are that come with it but they're not the reason I purchased the tool.
