Wow!! Why did I wait so long to switch? I bought a refurbished spray mate storm just to see if I could get it to work for my needs/ limitations. I have a birth injury that makes using most products a challenge. Having the use of one arm is the ultimate test for a companies product and let me say that I love this sprayer. I can operate it with no problems, just minor set up changes. Since this is working out so well for me. I am going to use this one for hardscape weed control and buy a new one for the lawn care applications. With the only change being a larger tank and pump to get the psi needed for some applications. The only drawback that I have found is the one I bought doesn't have the quick connection That others in the lineup do.
I don't write reviews very often so, it's safe to say that I am beyond impressed by the quality and usability of your products. There is no way I could recommend this to the level that it deserves. It is a total game changer.
