    • Great for large spraying projects. Saves time and comfortable to use.
Style: Base Model, Manual
This is way better than the stop-and-pump sprayers if you have a big project. First time filled it all-the-way up and discovered it was awkward to put on - sore shoulder and arthritis. Three gallons about right for me. I fill it and put it on a bench and back into it and I'm good to go. Used it to spray paint lawn. Worked great, just keep the pressure up which is easy with handle pump. Unit did not leak and held pressure well. ... show more

    • Game Changer for Spraying Weeds!
Style: Base Model, Manual
If you're wondering if buying this backpack sprayer is worth it, let me make it easy on you - Buy it, This sprayer is worth every single penny. Between weeds in flower beds, in the expansion joints in my driveway, and in brick sidewalks with lots of small gaps, I have to spray weed killer every few months and it is a hassle. I bought this to replace a 1 gallon pump that I had been using and would have to refill 3-4 times. The 4 gallon tank and the hand pump speed up work significantly. It is great quality - well made and feels sturdy. You can tell that they didn't skip any corners. The steel frame allows you to set it down easily, but isn't too heavy on your back. The straps and belts to secure it are very comfortable once you get it on. Even the screw on lid is solid and well made. It takes the pressure off of your back not only from not having to carry a smaller sprayer, but also because the sprayer heads spray as far as you need without having to bend over. If you have a direct stream you can spray it precisely, or a spread out stream you can easily pump while you spray a larger area. The different sprayer tips work extremely well and haven't clogged once. It sprays more than other sprayers I have used (which I personally like) but there a flow limiter attachment if you want to use it. ... show more

    • You’re here, you’re already looking for one; stop, get this one.
Style: Base Model, Manual
Should have gotten this years ago. I’ve got 2acres of land with a mix of gravel and concrete throughout so it’s bound to get weeds etc. I used to buy the 1gal things of killer until this year when I said screw it, I’ve gotta find something that’s easier to use and that I can use on my fruit trees. Enter this thing. Comfortable, easy as hell to use, more tips than you need, and a top build quality for what it is. 100% worth the money. Mix your own product and spray it comfortably with this thing. ... show more

    • The sprayer works as advertised
Style: Base Model, Manual
Design and ability to self-repair is a nice feature plus the multiple tips and it comes with a user guide in print The sprayer works as advertised. It can be quite heavy with 4 gallons. With adjustments to the straps, while empty, it is easier once filled to put in on your shoulders and buckle up the waist and chest straps. I personally leave one strap (left) as is without loosening it after my initial adjustments, then the other (right) just needs a tensioning to level the sprayer once I put it on the left shoulder.The padding of the shoulder straps is adequate, but more would be better for comfort. The pump handle is able to be mounted on the left or right depending on your needs. The hardware to attach the handle is more than adequate with the use of a thread in bolt and Nyloc nut to ensure it stays there. It takes less than 5 pumps to build up the pressure. You will pump it more than expected to maintain pressure regularity, but it is an easy no exertion action with your arm more or less lying on the pump handle. I sprayed a half acre of a fence line, 3 buildings, and walkways plus a 70-foot drainage ditch using two 4 gallon fills. The wand and hose are just long enough for me at 5'9" where I don't have to bend over to spray my target. There are multiple tips that can be used based on your needs, and as the manufacturer and others here have recommended, it is a good idea to put a gallon of water only in as a test liquid to pick out the tip you prefer. With my application of a concentrated weed and grass killer, the Fan tip (Red) served me well. The Brass adjustable tip would have also been acceptable for a smaller application area. Remember this: A US liquid gallon of water weighs about 8.34 pounds or 3.78 kilograms, so you have to be willing to carry that weight initially plus the weight of the sprayer. (approx. 13 lbs or 5.896701 kg). Totally filled with 4 gallons results in approx. a total weight of 46lbs or 20.86525 kg Would I recommend it? Yes, It does save time having to refill the smaller sprayers and measuring out the mix of concentrate for large jobs. Is it for everyone? No, The decision to go larger than a carry pump sprayer is strictly yours. ... show more

    • Great Value for the Price
Style: Stainless Steel Wand Upgrade, Manual
After reading about numerous manual backpack sprayers, I settled on this one. I'm glad I did. It works beautifully. I've sprayed about a dozen tankfuls so far and it does a great job. Don't know whether I'll ever use any of the various nozzles other than the adjustable brass tip - it does everything I need to do. The padded back pad is a huge plus. Having done many backpacking trips in my time, I can say this is quite comfortable. And I've not experienced any leaking or dripping during use. I've been perfectly dry. You do have to pump the handle fairly regularly to maintain a high pressure, but it really sprays well. Besides, a little exercise doesn't hurt. Definitely recommended. ... show more
