It works, almost too well. The fit is tight, and the material relatively inflexible. The naked Phone fits great, and won't go any where, but if like me you have a 'thin' rubbery (TPU) cover to protect the Phone day to day, then there isn't enough 'give' in the holder plastic to fit around the phone in the cover.
( At this point I reflected on living with the mount as is, ie taking my phone out of the cover I use to secure the phone in the car, and I realised it would grate. So knowing enough about tools to be dangerous I grabbed a Stanley knife, and fine metal file, and 'modded' the plastic holder so it would fit - and it does. However with benefit of hindsight, I wouldn't start from here. I probably should have just shopped around for a suction holder mount that could accommodate the Note 2 & was adjustable )
Other than that the sucker grips to glass, the flexible arm is firm, stiff with newness, and the plastic holder comes with cut outs meaning the camera etc & stylus can be used.
