It seems that some of these can be better with their suction and adhesion than others.These are ok for some of our grandchildren to play with, as a type of fidget toy. In that sense, they can be fun and useful.HOWEVER, I cannot recommended them at all if you expect them to be able to stick on a glass surface to hold a phone or small mp3 type player. They give the impression, initially, of holding on quite well. But that does not continue. Slowly, over a few minutes, they simply some away from either the phone or the surface they are attached to.In that respect they are very poor.As mentioned, as a fidget type toy, the yare appreciated. But most certainly not to risk sticking a phone to a flattened glass surface.If you do buy them, do so with caution.

These are brilliant, ideal for making calls, using for social media videos etcSuction is great, held my iPhone in place no problemGood value for money too
