Excellent value for watch lovers!
I used to take all my watches to my Clock doctor. Even though he never charged me for battery replacement, the trip was generally a chore although I miss the visits. This item allows you to do battery service at home with very little hassle. Just take your time and make sure you have the pins lined up and snug to outer case grooves. Bravo!

Decent tool fo the price
This is a decent tool and a very low price. It's obviously not a high-precision device, but used carefully can get the job done. I stress "carefully". If the tool is not adjusted to exactly fit your watch's cover plate, you're almost certainly risking serious scratches on the cover.

The unit I received was only "OK" Both of the adjustments worked smoothly, but one of the pin sockets did not contain a detent ball, so that pin was loose and wobbly. One of the other detent balls was stuck and I had to move it with a screwdriver before the pin could be fully inserted. I put a couple of layers of transparent tape on the pin base and that cured the "loose pin" problem.

However, the wood case is very nice. :-)

Don't bother
I guess this is a love it or hate it item. I hated it and I sent it back. It didn't come with any instructions. I guess I got a different tool than the people that said it was easy and wonderful. I'm a college grad and I couldn't figure it out. I emailed the company and they sent me directions but they talked about a vice..what vice? and how it opened up..it did? The pins had no way to stay in place. Too frustrating and it didn't open a thing. You know what did open my watch? A sharp knife! Worked like a charm and it was free!

Real nice for the price.
This tool really fits the bill...especially for the price. As previously mentioned, there isn't directions. But you don't need them. The tool is pretty easy to figure out. Just make sure the bits are pushed all the way in like others have said.
I had 3 watches that needed batteries...this has paid for itself already.

Poorly Made
The product is very poorly made. The bits don't fit very well into the tool and the verticle handle adjustment is very sloppy and loose.

However, the customer service was excellent when I contacted them and an immediate refund was issued.
