Bests & Worsts Reviews from Amazon

This is a positive review, but when I first got these I was ready to write a bad one. I solved the problem I was having. The indicator dot that slides from red to green when the suction is holding (a potentially fantastic and reassuring feature) was not working consistently. Where the right suction would move to 90% green, the left one would only move to about 25% or sometimes 10% green, or not at all. Yet it was holding. I tried different locations and the indicator discrepancy remained consistent. The right one would indicate correctly at a tile location where the left one did not. The solution ( done a few days ago - and it appears to still be working) : I gently rubbed a drop of body moisturizer cream on the indicator dot and voila.....the indicator is now moving to 100% green when the suction is working. When it's not working, it's on red. When it is holding, it's green. They need to grease these indicators up before they leave the factory.
