(5 out of 5 stars) Nice Board
Reviewed By: Bob S. from Pueblo Co ()
Pros: Was able to mount to the box with same pins
Cons: other than replacing the insulated sensor none.
I was really impressed with the quality of the board. I was replacing an old gecko board and this was the replacement for it. This one was real heavy built. The old one was to light to handle the load and melted some pins on the back of the board the components was ok just was no longer connected on the board. This one was a lot more durable in the contacts and the size of the board wiring. the kit required a little more work since you have to replace a couple of sensors but just get a good foam insulation and after removal of the old sensor use it to seal in the new one.
