It works great overall. Best features are the fill cap has a nice center handle, comes with multiple tips for various jobs, and I was very impressed with the kit of spare o-rings for repair work or tune-up after a few seasons of work. Only gripe I have is the button to lock the trigger is not easy to set or release. That could use some improvement. And I would love a waist strap for less rocking when operating the pressure handle. Otherwise, its a good deal for sure.

Works very well. Bit heavy when full but that wasn’t something I considered…much easier if elevated before putting it on

The sprayer came and was missing the little nut that secures the wand to the sprayer handle.Asked Amazon to send me one, but not sure they got the message.It worked fine, but without that nut to seal the connection, it squirted out a little thewhole time I used it. Guess I could try to seal it up with some kind of glue, but would reallylike the missing nut, if possible.

I wish I could give it more stars, but I can’t. The kicker…the weather hasn’t been good so this was my first chance to use it and I am unable to exchange/return the item. Now I have a $50 ish door stop! The installation was very simple, even though the instructions aren’t that great. Loaded the tank with weed killer. Pressurized the tank as explained in the instructions. Pumped it up until I felt pressure on the handle. Put it on my back and it started leaking onto my calves. The manufacturer provides extra seals and o rings so I decided to see if the leak was because of a torn o rings. Pulled the pump actuator out and got soaked with weed killer. I changed the rubber cap/seal on the pump plunger and took off the flat rubber seal between the plunger and the pressure tube. I couldn’t pull anything else apart so I reinstalled everything. Pumped it up again and it still leaks. I suspect there’s an issue in the pressure tube, but not certain.

I have had several sprayers this one is my new favorite. It came in the box ready to go and had some extra parts and spray tips. You press the Handel down or can lock it. The pressure is good and a good build quality with many functions on the sprayer tip. Ita not too heavy and the straps help distribute the weight. Over all grat value for my money and and would recommend to anyone who needs one

You often wonder about items you guess may work, these spray pumps are first class and a real value. They are built solid, easy to use and cost about 1/2 of what I find at the Big Box Hardware stores. Exactly what I was looking for to mix a pesticide in one and weed killer in the other. I suggest ordering the warning labels if you want dedicated sprayers, like I did. But this product is solid, heavy duty and small enough, at about 1-1/2 gal to mix a small batch at a time. We have spiders and blackberry bushes to spray, so I store the leftover mix for future use without worrying about leaks or damage. A 10!

The sprayer functions well but the design needs improvements. 1. The shoulder straps use clip-hooks to connect to the bottom support frame. The are free to slide around on the frame and will disconnect after the spring clip bends from normal use. 2. The shoulder straps need a chest strap to connect them to prevent the shoulder straps from sliding off the shoulders. 3. The plastic tank has three molded teeth to hold the spray wand when the sprayer is stored away after use. The design won't allow the spray wand to be pointed up as the spray wand trigger handle hangs below the frame. So, the spray wand has to be point down and that allows residual fluid in the wand to drip out; that's bad if you use blue marker spray additives to the fluid and that will stain whatever is under it.
