Finish-wise, this mount is nice and lightweight. It also installs perfectly onto my standard road handlebars without a problem. The main problem I find with this mount is that the X-lock attachment is not a perfect mating fit to the locking attachment on the bottom of the GPS unit. With the Enhanced Super GPS I tried, there is a slight rattle that is ever-present while riding.
There's a screw at the bottom of the X-lock mount insert, but it was already torqued fairly tightly, the rattling cannot be remedied by tightening the screw any more. This drives me nuts and necessitates some damping material added to the computer so that the rattle goes away.
The mount that came with the GPS computer is flimsy. I installed this mount on the handlebar but reversed from the default forward mount position so the computer is above the stem instead ahead of the handlebar. PERFECT!!
