High-Performance QP-000032 Chrome Plated Brass 32 psi Tire Pressure Monitoring Valve Cap, 4-Pack Review

Too long. I don't understand how long they are. My fault, but you still have to ask "why is it taking so long?" Looks like I attached pencils to the valve stems.

I needed a new set of sealed stem caps for my car so I bought two more sets for my daughter and grandson as Christmas stockings. I'm sure they are now made aware of low tire pressure, although they might not otherwise notice it.

So far Quick Pressure works as advertised. Easy for you and the wire to quickly detect low tire pressure. I would not recommend installing on massive valve stems where the length of the Quick Pressure extends beyond the sidewall of the tire.

2 months ago manometer installed and so far so good. They are all green, not red. No visible leaks. Makes it a lot easier to check tire pressure at a gas station. I will buy a set for my wife and my mother.

I have a large SUV with special rims and low profile tires that always seem to need air. Once they're in place, I just need to look to see if the print is okay. One caveat - they lengthen the valve stems a bit, so you'll need to check them after you've run them in an automatic car wash.

I put them on and they were great for two weeks. Then one morning I go out and find that my tire is flat. After inflating the tire everything seemed fine until the next day the same tire deflated. I refilled it and flipped the tabs. After that everything was fine, but I needed new tyres. After getting the new tires I put the tongues on and the next day my tire was deflated again. Each time I checked to make sure the device was screwed tight and tight. Good idea, bad design.

You know it's such a great feeling when I can get up, walk out the door, walk around the car and go to work without worrying about a nail I don't know I could pick up the phone yesterday or the day before. Also, I'm happy to see that my tires are holding air. No slow leaks. The only thing to keep in mind is the tightening process when sealing the sensor onto its O-ring. Be sure to hold the rubber valve stem, especially the old one, well with a tool and washers that don't cut through the stem…

They worked well for over a year but then I got a flat which I thought was because I drove over the glass. I checked my tire at Sam's Club and they couldn't find the slightest leak even though my tire was completely deflated twice. I thought either they were crazy or I was, but luckily it wasn't. As my tire started to lose air it finally occurred to me that it might be this pressure sensor because Sam had taken it off while checking my tire. So if you mount them on tires, be sure to take a…

Caps work great but there is a BIG problem. If you take it off to inflate a tire, you have to be very careful that the small black o-ring stays in the cap and doesn't stick to the valve stem. If it sticks to the valve stem, you will need to remove it from the valve stem and put it back into the cap. Because if you lose that tiny o-ring, the valve cap becomes useless and you can't buy new small o-rings, you have to buy a whole pack of 4 caps! This has happened to me several times. Last time at a
