Note: The supplier sent me a review sample to test, no attempt was made to influence my opinion of the product.
The Montar car mount is universal mount for smart-phones with an attractive glossy black finish. You get a pre fitted cleanable sticky pad at the bottom, you can wipe this clean with a damp cloth and let it dry, it retains the sticky nature on the pad.
You can fit the mount to either a windscreen or dash. There is a supplied 3M stick pad for dash fitting, you remove the cover and stick it down, then put the mount on it and lock it down. It won't mark the dash with the 3M pad placed there. The main jaws that hold the phone are just over 5 cm when closed and can open up to around 9.5cm max, they are spring loaded so close up around any phone fitted, with red rubber which has grooves to hold a phone in place without damaging it. There is a locking nut around the base of the jaws so you can swivel it around to the require position (tilt and angle)
I prefer to fit to a windscreen and the device was very solid when placed here due to the combination of the sticky rubber and locking it down held it securely in place. Even in warm weather there is no sign of movement or falling off. Do make sure to clean the windscreen before applying as they can build up residue over time. There is a tab at the bottom of the rubber mount to help removing it, it does take a bit of effort to pull it off, so make sure you use the tab to help.
A nice product, well built and effective. It's a bit more expensive than some other mounts I've tried, but to date this is the best built unit I've tested by some margin.
