I have an older version of the Gilmoure No Pre-Mix Sprayer, which I have used for many years. I took it apart to clean it and misplaced a part. So I bought this Gilmour 362. It is slightly easier to use than the old one because of the dial-a-mix features. I found the misplaced part to the old sprayer, which gave it to my son. He said he would rather that I had given him the new one. But he accepted the gift because all he had was a pre-mix sprayer that required several stop and mixes to get the job done.
