Now I have the Mini Gorillapod for smartphone already three months. Unfortunately I have despite the initial jubilation now arge restrictions on the functionality of the device notice. Above all, the ball head causes problems. Shortly after acquiring the product you had to turn the screw for locking not fixed, so did the head with smartphone. Now I turn the hinged wing nut (as I call times the screw for fixing the head in a certain position) reasonable force to stop and yet the head with the phone Schwerkrafr moved following further or simply slips through. The product is therefore actually to use only two stop positions, otherwise the phone folds down again and again because of the retention mechanism does not work anymore. Too bad that has occurred so soon after the warranty period. The product is available only to a small extent for me. Too Bad. (2nd review to wear after two and a half months)
