Perfect for what I needed it for - measuring conveyor belt speeds. Compared to my full size tach, it has much less variation in readout when reading the same conveyors.
My one complaint is that there is no way of keeping that little rubber cap on the top (even though I don't use it for radial measurements). I tried crazy gluing it on, and it still came off. Again, I don't need it, but I dislike having spare pieces for things.
One suggestion would be for a wrist strap. The first one I bought got knocked out of my hand by a carton going by at 540 fpm on the conveyor (it wasn't supposed to be there). I lost it due to the length of the conveyor and the high speed of the sorter in the DC. My husband drilled two holes in the casing of my second tach and put a camera strap through it. The next time I was measuring the same conveyor (you guessed it), another errant carton came by and knocked into my hand. Thanks to the wrist strap, I didn't loose it.
