There are 2 important factors that make this adjustable Garmin stem mount a clear winner: 1) no rubber bands that are prone to breaking or deteriorating, 2) angle djustability. The usual method of mounting that comes with the Garmin packages is a plastic mount with rubber bands to secure it. This may last 1 year (2 if you're lucky) then they break; and then you break (from falling) or losing it altoghr, especially if you're not prone to securing your mount with the tether strap. The adjustable mount easily mounts by replacing one of your 5mm spacers on your stem. The angle is easily adjustable using a hex wrench, and is solid and stable when secured.
