Just what I needed.
I needed a torque wrench for electrical work. This was easy to adjust, felt solid, and performed well. I easily tightened to 50 in-lb. I appreciate the calibration sheet. It increased my confidence that the unit is within spec. I would have liked a better case. What’s provided is fine to protect it and for occasional use. Also it’s compact. However, for regular use would be a little inconvenient.

Excellent torque screwdriver for small applications
We got one of these at work for determining our needed torque on some semiconductor test sockets. This tool really rocks, and beats the pants off the digital "toy" torque screwdrivers. This tool will actually cam-over when you hit the target torque, so you cannot over-tighten. It is easily adjustable, although it can be a small pain to hold the gold adjustment ring while locking/unlocking the torque setting. It fits whatever 1/4" bit you have, so it doesn't really limit you. NOTE: For those who don't know, ALWAYS return a torque-device to its lowest setting when you are done. Don't leave it at a particular setting, or you risk the spring mechanism taking a "set."

Well-thought out, but can't always loosen what it tightens.
Fantastic! High quality. Very well thought out. Easy to adjust and lock in the torque setting. For better and worse, this screwdriver is bi-directionally torque-limiting. (good for left handed screws too) Some times, it can tighten a screw, but torque-limits when trying to remove the same screw. I would greatly appreciate a right handed version with higher torque for loosening right handed screws. (Maybe about 25%-50% extra torque)

Solid tool. Trouble using it at first but great now.
At first I couldn’t get it to release my bit the black part that “locks it in” seems to have slid down further that it was supposed to (maybe happened when I was tightening my screws) but after looking at the product description I saw that you are supposed to push it up so I used some pliers to finesse it up and it released the bit. Now it seems to function properly. I used it on my pistol optics. Seems very solid and well built. Comes in a decent case to protect against damage.

Works good, intended for light torque like rifle scopes
Works good!

Pro Tool
Another Buy once/Cry once. I belong to the cheap rifle/premium optic school of thought. (Ya can't hit what ya can't see). The very price of premium optics demand a modicum of care if you bled when you paid for it. So a few extra bucks spent on a tool to guarantee a meathead like me doesn't snap/strip/cam a screw, distort or damage the optic tube of my investment means little to me. +/- 6% error vs Fix-It Sticks 10%. Plus I don't have to carry an assorted multitude of them. Range of settings, cheaper, more convenient, more accurate, highest quality. Save your Fix-Its for your WalMart bicycle.

Nice Tool
If you need an inch-lb torque wrench, this is a good one. I’m happy with it so far - no complaints.

Très bon produit, malgré une prise en main qui glisse un peut pour de forts serrages. La clé fournie avec aide pour le serrage, mais on à un peu de mal à l'insérer dans le tournevis. Malgré ses petits défauts le produit est conforme aux attentes. Pour le prix je recommande. Je suis satisfait de mon achat !

The seller was 100% and the quality of the device was excellent. However I omitted to check the units the item measured in. The seller accepted my return with full refund without any problems at all. I was very impressed and thankful for his excellent service.

This has had quite some use. Still holding up well. Consistent torque on the screws. Would buy again if I lost this one.

Works as it should it is well built , comes with certificate, worth the money. You can buy a cheap one but you may get false readings and ruin your instruments
