What is best: Compact size It has a good Cover Easy to operate Good build quality A good tourch to see your air valve of the tire.
What can be improved: -Product cover should be a bit bigger, it’s hard to pull out and fitting back the product in the cover. -Screen to check Air pressure is too small, may be not visible for senior citizens or those have week eyes. -that screen don’t have backlight, means you can’t see air pressure numbers in night. You have to use your mobile’s Tourch.
