ANKI HAPPIGO 4Pcs 32-to-35 PSI Car Tire Pressure Monitor Valve Stem Caps Sensor Indicator Easy to Read 3 Color Eye Alert

Works great as described. Quick glance tire inspections.

very pleased

Good product

It turns out that by design, the 32 psi caps won't plainly indicate low (red) pressure until it reaches 24 psi and that's too low for my application. I'm now more concerned about the chance and consequences of one of these leaking so I'm sending them back.

Nice made product. Easily installed. Works as advertised. Shipped/received fast.

As soon as I received this item I should have known better than to put them on the car. All you need to know is that the instructions say that if the car gets wet or goes through the car wash they should be removed. To me this doesn't really seem like a reasonable request but I still gave them a try. Fast forward to only two months later and after checking the pressure of the tires I realized that the color indicators themselves didn't change color despite one of the tires being very low in pressure and even worse is that all four ended up being corroded to the valve stem which required pliers to remove. On top of that one was so corroded that it broke the valve stem itself so now I need to take it into the shop to be fixed. Never again....

Love it, ThkYu!!

I loved the idea of these but all my tires kept showing as low periodically especially after a sudden temp change and when I took them in I was told that some of these types of caps allow for slow leaks. So I went back to my originals. So far my sensor isn’t on and it’s been a few days.

I noticed that my front right tire is under inflated but the indicator is still showing green. Imagine my surprise when I checked the pressure showing 18psi, when all the others are at 36psi. This is a dangerous tool that gives a false sense of security.

nice product i have no complaints

Muy compacto y específico Llegó en buena condicion y en tiempo Funciona perfectamente y se logra ver a buena distancia, perfecto para mí bicicleta y motocicleta 👌

Unos meses de uso y empezaron a perder aire y a desinflar en pneumatico

Lo instale en las llantas de mi automóvil y ya no me preocupo por saber si traigo poco aire en las llantas ya que esto me lo indica cada vez que paso por una gasolinera.
