Even though it has a 4.3 rating on, it’s a hard-fought 4.3 rating throughout 147 reviews that gave it all sorts of negative reviews. One Amazonian user thought the reviews were so bad that he’d be sure to return it. Its design is too simple and low profile for a commercial release. It also produces a lot of noise that you have to deal with earplugs. The belt also wanders all over the place, thus many users have a difficult time keeping it on track. It’s advertised as adjustable, but it requires load of adjustments in order to be a workable power tool.
