I received the Travelsafer Tire Gauge for a large discount in exchange for my honest opinion.  I found that this tire gauge is very helpful during day and especially at night because it lights up.  There is a blue digital screen that comes on when you press a button that will give you the psi air level of your tire. There are other options too like bar and kgf that I am not sure what they are. Maybe another countries way of measuring the air level? So I only use the psi reading.  Very easy to see when holding the handle. You do have to sit on the correct side of the tire though or the gauge won't connect to the air hole.  The hub cap is in the way on one side.  It is very easy to grip  and when you line it up on the right side of the tire, very easy to use.  It took me a couple times to get the gauge on the air hole correctly because the air kept leaking out. The directions say to press firmly and that seemed to correct the problem I was having.  Make sure you line it up right too or air will leak.  Not the gauge's issue, just me not doing it right.  I tried this tire gauge on our car tire, but it can also be used on a bicycle and motorcycle.  It runs on a 3v lithium battery and is made out of plastic. Kids got a hold of it and started banging it around a little and it held up! Oh and it is very light weight.
