I have used this speedo in a Losi XXX-CR, then a XX4 and finally in a 12th car. It performed perfectly in each car, really good speedo. It has a small scratch on the top of it, I've tried to show this on the picture. I did it by stupidly slipping when trying to remove the stick on heatsink after using it in the 4WD. Doh! It doesn't affect its performance. Last thing to mention is the cap has a dent on the bottom but again doesn't affect the performance of the speedo.
I'm looking for £45 (as a gift) posted.
