Product is absolute rubbish, holder needs adjusting with a screwdriver if another same model phone is mounted even with just a 1mm difference, so don't bother if you have more than say one iphone of the same model (never mind a different phone)with very slightly different skin/case on it as it will either rattle around or not go in without getting the tools out, product not thought through, I'm trying to return for refund, waited weeks to arrive as out of stock but they never pointed this out after giving me the order link!
