I've only used them a couple of times but once set up they work well. I wish there was an easier way to install them, but once you get the hang of it, installing them isn't so bad.
Easy to set the pressure you want and works great. do not leave it in place while driving; blow off and remove. I regularly check the pressure with a pressure gauge as the tires warm up and the pressure rises.
These things work very well. I've used them twice and they work well. At first it was a bit difficult to figure out how to set them up. The instructions that came with it aren't the best. I watched a YouTube video and after that there was no problem.
