Very good thus far. Used to mount scope to rifle for correct torque. Have only used twice but optimistic for continued success and quality.

Not bad, except one thing!

The tool is pretty much what I was looking for except one thing... the receiver where the bit goes needs to be able to lock the bit in place. Every time my guys are using it the bit keeps coming out, makes it very frustrating!!! One other thing, now that I'm thinking about it... it would be nice if when it broke torque you could feel it better in the screwdriver. It is so lite that your not sure if you broke torque or not.

Haven't had a chance to use it yet as I'm planning to use it for gunsmithing, just haven't gotten back to it yet. Played with it a bit and seems to work great. Love it. Thx Dan Brown

Best I've ever used.

This torque screwdriver is an awesome product. I have two other competing products that I frequently use in precision electronics work and the Olsa is by far the best of the group. I really like the torque adjustment, it is easy to read and easy to set. I'm also a fan of the included T-bar that attaches to the handle and allows you to get the extra leverage you sometimes need at the higher end of the torque range. I also like the twist-apart case that it ships in which allows me to throw the screwdriver in my toolbox drawer without worrying about it getting damaged. I don't have a way to test the accuracy of the torque settings with precision, but I tested it against my other two brands and it was consistent with them throughout the range. The Olsa is heavier than the other two I have and feels like a substantial, quality built item. I highly recommend this particular product!

Fits where others don’t

Never knew how handy it was to have a torque screwdriver. It will get into places where a regular torque wrench just won’t fit.
