Review on Sierra 58255P Tach 7K Amega by Keith Aluguvelli

Installed in dock and worked fine. After about 2 hours, the actual use of the water block failed (the inside of the helmet never got wet or hot from the sun). Threw away the package so I have to eat $50. Foolishly expected more from Sierra. Update: I never bothered to remove the touch, but yesterday (months after the outage) it worked. Maybe you just need to shake things up? I soldered all my connections so I doubt it was the wiring but who knows. Improve rating to 3 stars.
