Review on LONDAFISH Electric Vacuum Cleaner Operated by Sarah Brown

Used to perform a 25% water change in a 35 gallon tank. I actually read the directions, kept it at the right water level and got it on August 4th, used it every other week when I did 25% water changes and now it wouldn't turn on. decided to see what the problem was as it didn't even spin when I tried to spin it by hand. I got to the motor and everything is corroded and the b4 sumone is trying to say it's because of the batteries I've only used with the power supply. It was handy when it worked, but it didn't cost $20 every other month. It's just that the motor doesn't have enough water protection and it's only a matter of time before it stops working.
