QP-000095 Chrome Plated Brass 95 psi Tire Pressure Monitoring Valve Cap, (Pack of 4)

They work well and are easy to read

I used this on my motorhome, where tire pressure is fairly critical.One leaked right away so I removed it.This last trip, inspection showed 'Green' then I drove 120 miles only to discover that the tire pressure was actually 23 psi and not 95 psi.Poor build, expensive, would not purchase again.

Good quick reference to be sure you do not have a low tire at a glance before starting out, or at a rest stop. You do have to move around a bit to see the red/green band area depending on where the tire rotation stops. Gives a "warm fuzzy" without the expense of electronic digital readouts, but without temperature readings. Not a bad trade off to me.

One of the four caps did not work. The other three seem to work.

I purchased 2 sets.Even at 100 psi 2 of the sensors kept showing red instead of green, so I didn't use those.From the remaining 6 one had a slow leak resulting in a flat tire.

good product

Three out of six showing red instead green, all received 98lbs of pressure on my motor home, took it for a drive as suggested in instructions but still the same red reading.

I think these will do just fine for the price.
