An ad for these comes up every so often. https://www.ssl-stormerhobbies.com/c...=ns&pn=MRT1000

Anyone use these, any problems with lap systems at your local tracks?

I'm looking for a transponder for the upcoming season.

used one for a season no problems

Why not spend 10 bucks more and get the real deal...the original mylaps rc4 system from stormer

AMB is choice but seen many use MRT with no problems
