Works pretty well for its price, takes a minute or so to reset fully sometimes. Tested initially in my workvan and it was almost perfectly accurate (Like off by 2 - 4 km/h compared to the speedometer in the van.) despite only being on like 4 - 5 satellites rather then the required 7. Certainly took a bit to get signal though in that car, but exposed to the open air.

Certainly took a bit to get signal though in that car, but exposed to the open air & not in a giant metal box with a window. It's maybe 5 - 10 seconds & it's ready to go instantly. Uploaded a pic of the test result i got on my vintage Tamiya Boomerang with a random brushed 550 motor on a brand new 2s lipo, but seems the upload is broken or doesn't like jpg image format maybe. Tried a second one of my thundertiger/varicom pandemonium which has a 20t 540 motor in it at the moment.
