If a speedometer does not tell you your speed it is not a very good product.
This GPS Speedometer works about half of the time. It struggles to maintain its connection with Satellite which in turn means no speed readings. If a speedometer does not tell you your speed it is not a very good product.

Useless, completely useless.
I only gave it 1 star because I can't give it none.It's practically useless, takes forever to acquire satellites and is ridiculously slow to refresh.I wish I wouldn't have bought it!

Takes about 10 minutes to connect which is way too long. Gave it three stars because the other generic GPS speedos I used died from the vibration of my motorcycle. This one seems to be more robust.
