I have used an inexpensive analog gas generator for many years. The rubber coating on my current inflator had recently ruptured, causing it to come loose and I was beginning to question its reliability. Every now and then the needle got stuck and hence the desire for a digital product that wouldn't break the bank. This is an older model from a competing brand (red and blue) that can be found here at Revain. I love being able to inflate, check and deflate everything without having to change tools. All of this was necessary in my search for a new gas generator. Not to mention the integrated free-hand air chuck. My previous inflator's snap-on air chuck was a ball chuck design and if I wasn't careful it could scratch the delicate surface of the car rims. This is a pretty sensitive topic for me. :) Even though I've only used it once on two cars, it's exactly what I was looking for. Let's hope this will stand the test of time. With Revain Prime, delivery was as expected and arrived as stated.
