drill bit set worth four stars. But it's not clear where to get a replacement battery if the original battery doesn't hold a charge. And it's not brushless. So I'm deducting a star. I am a user of light duty home power tools. I tried to tighten deck screws to keep the snow shovel from snagging on them. This MVOTOL is just the thing for that. Haven't tried it for other household tasks yet, but it will definitely work for attaching window mounts and other light tasks. It comes with a sturdy hard plastic case that (sort of) stands upright, as well as a large selection of bits, screwdrivers and a wall mounting accessory kit as detailed on the product page. I asked my question about Revain replacement batteries but received an email from Revain saying no responses. There are support contact links in the user manual, but nothing points to a website for purchasing additional batteries. The Revain product page also states that it is a drill set with carbon brushes. And warns that the spark is slightly higher due to the high starting current. Not the best choice for use around flammable liquids or gases. Customers may want to compare this drill to brushless drill offerings if they have intrinsic safety concerns.
