Delivered promptly and good value for money. Doesn't look or feel cheap, yet it wasn't an expensive item. Arrives assembled to fit an M8 without case, simply pop out a plastic insert to increase the capacity then it fits the M8 with it's stock case on perfectly. In landscape orientation just sit the phone into the holder and flip into place the hinged, foam-padded clip at the top of the holder. The main body is attached to the adjustable arm by a ball joint giving ample adjustment. The arm then has a normal elbow/swivel joint which meets the suction cup. The holder has a short length of charging cable attached which plugs into the phone, your long lead (supplied) then plugs into the back of the holder. This is a bit fiddly, mind you.
Solid enough, no vibration in use, loads of adjustment and no more taking the case off for car use. Also supplied with the little dashboard disc to suck to, but who uses those, right?
Great product, don't spend loads on a fancy one, get this.
