Bests & Worsts Reviews from Amazon

After telling me they replaced batteries, I took 3 watches to the store where I had purchased them. After a few days, they called to say they could not remove the backs from any of them. Several people tried, but couldn't. Loving a challenge, I ordered this kit & was able to remove all 3 backs. 1 was hard, but the other 2 were quite easy. There are several tools & instructions in this kit. The feeling of accomplishment was worth the cost.
