Bought it Feb 2018.
Mid June 2019. I've just finally got rid of this olixar phone holder because the sucker plastic has half torn away from the hard plastic of the suction mounting disc. The weight of the phone and arm basically peels the sucker away from the windscreen.
It's lasted 14 months, which i suppose is ok.
Cradle is working fine. Arm is fine too. It's just IMO a poor design of how the soft plastic of the sucker itself attaches to the rest of the suction mechanism and arm.
The cradle rotates between portrait and landscape and has a small sliding locking latch. It's a bit fiddly though and will only lock at horizontal and vertical (took me a while to work that out).
The feet of the cradle slide outwards, which is a nice touch. Gives support to wider phones and can handle different placements of e.g. headphone jack or USB ports.
The cradle grips (sliding) mechanism is smooth.
Arm is fairly long, so functional in that respect. There's a bit of vibration due the leverage of the long arm. Not too bad though
One of the pads of the side grips (bits that 'hold' phone) came off almost straight away but the glue seemed ok enough to mean i just put it back (it's not come off since but does feel much of the time that it could fall off, when i pull my phone out of the cradle).
So, a mixed experience, really. For all these reasons, I've only given it 3 stars.
