I bought the Gilmour because it was recommended to use with the Spray & Forget House & Deck product. When it came, we could not figure out how to convert the measurements to use the product in this sprayer. When I called Customer Service at Spray & Forget I was told that I CANNOT USE THIS SPRAYER with their product!! They don't know who linked it here on Amazon and they have been trying to get it unlinked to no avail. So, if you are buying SPRAY & FORGET products, DO NOT BUY THIS Gilmour Sprayer!!
