You get what you pay for
This unit wasn’t expensive so I am trying to be reasonable in my review. It’s something you might expect to get in the trial size aisle at a retail drug store. It’s simple, comes with the battery, and some extra parts. My battery didn’t work and the directions weren’t clear as to the direction of the battery so that took me some time to figure out. The worst part of the design is that there is no real power button. You just effectively tighten the battery cover and it turns the unit on. It’s fine for what it is.
