I wish I'd found this device 4 years ago! Yes, it's a little pricey, I think, but it has already saved me so much time! I regularly spray Garret Juice Plus and Alpha-Bio Thrive (and even liquid CGM) and I have a pretty big yard...close to 10K square feet. A hose end sprayer doesn't work, because the concentrate that I spray is just to thick, and by time you water it down, it takes forever to get enough of it on your yard. And trying a hand pump is just going to result in shoulder surgery at some point! This PECO device is perfect! It is faster, easier and far more effective!
