A part of the review has been auto-translated.
The second one is working great. I thought the display might not be visible in the sun but it is. You can see everything great at night and in the daylight. If the sun is hitting it directly just block the sun with your had and all is good. I like having the time on the display but would like a 24 hr option. It is a comfort knowing your tires have pressure before riding without having to check the pressure every time like you should. The clamp works gets and is a quick release. The display screws off the mount quickly and easily. I have to take the caps off and check the accuracy with a pressure tester but I know they a close since I pumped both tire up to 34 psi before installing. I did lose a little pressure when installing. I also like that it goes to sleep when not using but wakes up as soon as you move the bike.
All ok thanks
