What I can say about these other than they are very functional, add some extra security to my watch whilst charging, and go along way in protecting my watch whilst charging against my cat ?.They are made of very good quality silicon and therefore can only be destroyed by applying deliberate acts of vandalism, or in a house fire or such disasters, no doubt they will out live the life of your watch, at which point they can be used as a mobile phone stand or as a DYNA VAP cooling station - get creative with your idea's these just sprang to mind ?.I also bought the TiMOVE pack of colour co-ordinated chargers, haven paired the chargers with these stands and I do not have any of the issues mentioned by other reviewers, I can pick my watch up by the straps and shake it, and the watch still remains firmly attached to the chargers whilst placed inside the stands.FYI the chargers are on par with the original with fantastic magnets. They are not quite as long in length though and are plastic coated without the tactile silicone cover on the wires, however this does not affect the functionality in any way, whilst placed inside these stands the anaesthetics aren't an issue either as the wires are hidden.
