exellent and easy to use with a clear and crisp sound
however i noticed while driving the other day that on some car sunvisors( i.e golfs) that it does have a tendancy
to fall off the visor when you have the visor down.
to resolve this problem i bent the metal bracket in a bit that seems to do the trick.

find the toggle switch a bit of a fiddle to use when driving and also when accessing the menu to enter numbers, but overall not bad, although sound qualities leaves a bit to be desired. I also won't be throwing the instruction book away for a while as making changes and adding extra entries is a bit too complicated, should and could be easier.
