You know, Don, I'm less than impressed with this gage. The stinkin' center tube only goes to 1" total. the base of the gage could have had a bit higher ridge to make placing the inner gage easier and hold it so it doesn't flop around while you try to put on the larger collector at the top. The other thing is that they could have added some markings to the big part of the gage for rains over 1". The fact that you have to pour off the first inch and then refill the inner tube several times for rains over 1" makes this very inconvenient. This gage could have been made so much better with a minimum of effort, but they didn't do it. I could never recommend this to anybody. I was truly disappointed when I removed it from the box and started struggling to put it together.
