Great product. Very robust and good quality metal has been used. Very similar to RAM mount but much cheaper. Drove my bike at almost 100+kmph with the chevik phone mount holding my phone in place and I was surprised at the strong and sturdy grip. Phone was held safely in place. Same goes for bad road conditions, the ball loosened a bit making the phone support itself on the handlebar but it didn't fall off.
Only big drawback i find with the product is the charging cable. Frankly i did not need it but it is not detachable and hence I am forced to tie it up in a bundle behind the mount which is not very appealing to look at. The charging/ usb port should be made detachable so that it is installed only when required. Rest its a great product. Go for it.
