Review: Great DIY Sprayer for the Lawn Enthusiast - Used this for over a year without any issues or leaks. I love that I can use my existing Milwaukee battery to power it. It can get heavy when filled, but the straps are beefy and have plenty of padding.
Review: Very nice! - Did lots of homework and 4 sons is top notch . Everything I own is Milwaukee, almost went with one of them, but this is best of both worlds in my opinion. Or diff battery pack if you’re a dewalt or other. Very comfortable and convenient. Can’t belive it’s taking me this long to get one.

### ⭐⭐⭐⭐⭐ Great DIY Sprayer for the Lawn Enthusiast
*by F***S on June 21, 2025*

### ⭐⭐⭐⭐⭐ Very nice!
*by R***N on May 15, 2024*

### ⭐⭐⭐⭐⭐ 7 Year owner experience - a follow up review
*by J***T on July 16, 2024*

This is a follow up review to my original review when I bought this sprayer over 7 years ago. I have used it for everything from spraying weeds to applying mold control on roof shingles of my 2-story home. Over the years I have added the longer 15’ hose, the 14’ telescoping wand and, most recently, the 4 Boom Sprayer. My son and I used the boom sprayer last weekend to apply RoundUp. It worked even better than we expected. The boom sprayer came in a ziplock bag with no assembly instructions but it was easy to figure out and set up. We attached it with a bungee to the rear rack of an ATV, locked the trigger open and slowly drove down all our forest trails and food plots while it applied a nice, wide, even, herbicide spray. I am still totally pleased with my sprayer and have nothing but compliments about this company and this sprayer. The service and responsiveness from the owner, Lance Ensign, has been exceptional. He has always responded quickly with a solution to any issue. When I lost the cap to my sprayer, he sent me a free replacement. When my battery died, we discussed the DeWalt 20V tool battery replacement kit that he was developing. The kits were not yet available but he sold me all the parts to make the conversion and included very detailed instructions with photos. It was an easy install and worked perfectly.
