My speedo stays cool. with the V203 even 1 led cooler than with the V200.
Now only 1 led blinks and before it were 2.
I clean my speedo once in a wile. (it's the only thing I clean o my car)
I do this because I almost burnt my LRP TC because of it.
With the LRP I had to do this every week because els it started to give problems.
With the Tekin I do this once a month.
A club member burnt his LRP speedo 2 weeks ago and doesn't get a new one from LRP because the speedo was dirty.
Now I find that the Tekin speedo stays much cleaner inside than the LRP but still there comes some dirt in and I don't want the same problems as with the LRP.
