great for the working one, the other one got refunded because it kept shutting off

best to buy when on sale, they fail after less than a year of use.

Works well, when used as intended. Make sure you use good batteries with it. Tends to like Alkaline more than any other type of batteries. Make sure you use the proper soap too.

it doesn't work properly under certain setting, eg. when put aside a sink that's white and with bright light setting in the room, it doesn't sense properly, need to keep pressing the power button, but if put aside a dark countertop but in a dark room, it will work properly.

I like it.

I would give five stars if it's last much longer...I like the machine as long as working well.
