Love this inflator. I bought one and loved it so much I gave it to my dad and bought myself another identical one.
One thing to know about it is that when it's attached to a tire that has some pressure in it already, you may need to hit the start button a few times before it will kick in and overcome the latent pressure. I guess I haven't owned it long enough to know whether it gets more finicky with wear.
But it's so compact I can keep it in the armrest of my 2009 Explorer. That means a lot.
