When I did a search, I discovered the cheap ones I used long time ago…..and then the “quick pressure” brand which seem better made.
Yes, the quick pressure seem better made, however, one tire blowout which could have been prevented is not worth the savings generated by getting these versus a real TPMS.
I really wonder how easy it is to see the color band in the little cap. Looks like you might have to get down on hands and knees to check each one.
The other issue is you won’t be notified of a leak happening while you are driving.
If you get them, report back how they are working.
