I'm sick of people hating on prosports. They are an excellent value, maybe not top of the line, but cmon!
If your gauge is broken, they have excellent customer service and will fix it right away. Mine has not had issues. I would reccomend them for sure. Save the money, get a slightly less "shiny" gauge, and put the money you save into something more useful.
They are the same as many other gauges that come from China...I think I've seen them branded as "glo-gauges" as well. I don't recall the exact name, but it was the same as those in my mx6. People hate on them because they are relatively poor quality (not saying AM Phantoms are much better these days).
In the end, you get what you pay for. The Stri gauges look a lot like DEFI knockoffs.
As for my 3 Prosport gauges, I've had to send my sending unit for the Boost gauge back twice...
They do have great customer service though (cool)
