I was going to replace the suction cups as I took the original pair on an off enough times that it doesn't stick very well. It came back to life after cleaning it with some soap and water. The problem was I didn't know where did I put them. After a little bit of searching, I found Ace Hardware has small suction cup that fits (just need to take the hook out) for 59 cents a piece. Seems to do the job well so far.
What other suction cup do you guys recommend?
