Review on Double-Sided Nano Traceless Tape: Removable, Reusable & Washable Adhesive For Home Decor, Wedding Cars, Photos & Posters! by Mark Raj

These are alright, but they don't hold everything as well as I'd like and you have to make sure that what you are putting on it is completely clean or else it won't stick.I mostly use these to stick notes onto the cabinet with at the moment.I also have one on the fridge, and one above the counter on the wall. I have tried to hold my phone on them, but they eventually let go and my phone drops.It is good for short term use but not for long term use for holding a phone. I don't think it would hold something heavier at all.If you have them on a flat space and just want to keep it from moving around, like on the dashboard of your car, then they will be great.These are sticky to the touch. Have not tried cleaning them yet but I imagine that would work just fine and keep them workign for longer.
