Bests & Worsts Reviews from Amazon

They've been installed without falling for almost 3 weeks now. They fell after a day for almost a week straight then I started getting online to see if others were having the same issue, which I saw a lot were. You have to keep tightening these a few times a day for the first few days and it also helps to damped the back suction cups before installation and after you clean both surfaces. I was about 1 try from returning these but so far they've stayed, so I'll monitor these over the next few weeks. I would give a 5* if these would have stayed from the very beginning.
