Check out this thread about MRT PT's. I'd like to sell all of mine and get replacement clones as these are the best in PT's. A guy I race carpet with got a couple and has never missed a lap that we have found. Also they hold power for a few moments after the battery is turned off, something internal. I haven't read all of the in and outs yet. I did read they're offering non-clone PT's now too. If I had to start over again I would choose these. IMO
