I will stick with my routine pre / mid trip checks and a solid tire valve cap.

It happens because of faulty installations. There is a small rubber O ring inside the cap, that makes the seal. Put them on too loose and they leak. Put then on too tight and part of the O ring squeezes inside the lip causing a leak. You put them on snug and spray the stem with soapy water. If no bubbles, there is no leak. By the way the leaks are usually big enough you can hear them and usually the tire will be completely flat within an hour. I used them on my RVs in the 80s and 90s and found them to be trouble free. I did find several in the packages that leaked when first installed. I just took the back to the auto parts store and they replaced them. I have has four on my golf cart for 4 years and they work fine. The biggest problem is they only work for one pressure. If you change tire sizes or rim.s or tires you have to buy new caps.
