The price was decent and I like the color. It is easy to get started and it came with batteries which was unexpected and nice! Like others have said, it doesn't stop on it's own like it's supposed to, which is my only drawback with it. I had thought that if I pushed the button on the top it might stop it, but all that does is reverse the direction of the opener. 4 stars because it does work, but having to fool around with it to make it stop makes it lose a star for me.

Not bad at all

Color: Green/Battery

Super EASY for my 83 old mother with arthritis to use. It’s not “speedy” but it works great.
