My husband likes working on cars, he has an air rachet and plenty of normal sockets, but often spoke about getting a battery powered Ratchet. They all seem very expensive, we couldn't really agree on one as the money most cost was too much for all he would use it for. We then came across this one and decided to try it as the price was more reasonable. He is very happy with it, says it works great on bolts etc around the engine rather than having to do most things manually. It wouldn't be recommended for doing wheel bolts etc but works great on other bolts. The battery seems to be going well so far. Just hope that in the future if needed a replacement battery can be easily obtained for a reasonable price.
