Was searching ebay for a used JB+ and found these guys. Googled the internet and NAM and nothing really came back. Has anyone heard of them? Could they just reverse engineer a JB+?

I saw that too. I don't know anything about them. I haven't had good luck with knock-off items in the past. So, I ended up buying a JB+ from ECS today along with a Sprint Booster.

Hey @Kcyotz question is the sprint booster worth it ?

Wish I could tell you. They should be here this week. But, we've had crappy weather in KC the past week and this week. So, I don't know how soon I can install them to find out.
