They are very easy to see at a glance

I was wary about trying these but after seeing a tire go low that i wasnt aware of and due to having a couple of missing valve stem caps i decided to give these a try

And wow i am so happy with em

My one concern was that they might actually contribute to air leaking out of the tire weve all been there while checking the tire pressure you accidentally let about 5 psi escape because you are too slow or clumsy to get a good seal on the gage
