I have got through lots of car mobile phone mounts and some are very good however if your smart phone has a protective case many wont fit and you resort to a universal clamp type which are generally naff.
In my case my Galaxy S5 wears a Tech 21 protective cover which is brilliant. Anyway was in ASDA yesterday and saw the above. Tested it on my phone and its sticks like the preverbial to a blanket.
Easy to fit and it looks like a realy well thought out accessory. Best thing is you will only ever need one as the adhesive pad will attach to the back of all phones and sat navs. At £5 well worth the outlay.
