5/5Awesome product and great customer service
Reached out to LapMonitor about some parts and technical help and customer service was excellent. I had a kinda weird request and was surprised that they went the extra mile to help. Product works great and is an awesome tool for tuning on practice or race day.

4/5Love this system!
I do love lap monitor it is a great system. Love racing the ghost when i dont have someone else to race with. But i gotta give 4 stars, because for the actual device, is an on/off switch too much to ask?? Also im going to have to research this as maybe you offer this but a detachable transponder would be nice. In other words, the IR transmitted could unplug from the transponder piece that plugs into the receiver. Would make taking the body on and off easier rather than having to put the IR transmitter into the body every time. Otherwise i love the whole system and works great

5/520,000 laps & going strong...
Our cars ran over 2,000,000 meters during the 2019 season and the Lap Monitor transponders endured multiple, high-speed crashes and weather temperatures over 100 F... Displaying the lap info on a big screen adds to the enjoyment for everyone trackside... We had been waiting decades for this type of small, yet powerful technology to hit the market... Thank you for the fun and the smiles...
