AMB Rechargeable Transponder

Exactly as described. So far, I used it for half a racing season without any problems. I'm glad I got it. FYI, first time you charge it, give yourself at least 24 hrs. It took a long time to fully charge. After the first charge, it's much less.

good price,,

Reliable and accurate, this transponder is the best in the industry. The included mounting and use instructions are very easy to read and make installation a snap. Excellent online support available if needed.

Works great. It did not come with instructions but it's pretty self explanatory.
