Maybe but it is small and not really easy to read. it is only 2.5 inches in diameter and that includes the case. The indicator lights are small too. Besides, cost is subjective on what a person likes and how well it works.
The koso one is electronic, therefor you do not need to worry about guessing at the ratio to hope you get your speed right. The koso uses a modern speed sensor that takes its reading from physical movement of the whichever wheel you mount it on. It has an easy to read speedo and tach.
You might call it expensive but so are the dakota digital speedos and I feel this is a better unit.
But it is just OUR opinions. I was just showing another option. I know some people have used the koso and really like it. So, if anything, it is not junk.
The ride IS the adventure. The destination is just to get gas!
