There are over half a dozen slightly different kinds, for $20 to almost $100.
Seems like an easy way to get an accurate speedometer for multiple cars in various states of build, independent of finding the proper trans gear.
I'm currently using my phone, but the battery drain is pretty severe.
The main question is- are they accurate?
