I bought this gauge because of the warranty. Well, it turns out to be useless. I emailed them a few weeks ago about an air leak from this gauge (not from where you put the clutch but from the main body). Didn't get anything back. Just buy $10 from Harbor Freight, this one has served me for years, this one broke right out of the box and Rhino isn't responding. UPDATE: 11/10/18 It broke. Misreading, sticky sentence and rotation of a set of words!? Rhino still cannot be contacted. **UPDATE** It's been a few months, I've used it about a dozen times, and it can no longer properly grip the valve stem and hence leaks air every time I fill up. to manually hold it onto the valve stem to inflate the tires. SO AGAIN. Buy Harbor Freight for a fraction of the cost. The only thing that differentiated them from each other was the guarantee. Which, as I said, doesn't exist because I can't contact this company YET!? **
