Very Well Built
My only complaint is the opaque color of the tank makes it difficult if not impossible to see the water line as you fill it up. It does have markings for gallons / liters... but not sure why because you cannot tell where the water line is. That said, very good quality and probably my favorite part of this is that it folds to a very low profile which makes storing it much easier. I've had several different backpack sprayers, this is by far the best.

Sucks all the way around.
Hated this sprayer. Used it twice before the internal pump separated into two parts within the tank. Shoulder harnesses were terribly uncomfortable. In addition, and I’ll preface this by saying I am not a large guy, average size, average build, the pump handle sucks! It’s so incredibly close to your body as you pump, it’s hard not to snag it on your clothing. If it were cold out and I were wearing something even slightly bulky it would be a no go. Keep shopping. This is not the sprayer you want.

Good for herbicides and other chemicals
We bought this sprayer for mixing and spraying glyphosate (grass and plant killer). It prevents inhalation secondary to mixing, and the sprayer requires less pumps to activate than our other sprayer. Our Roundup sprayer cracked even exposed briefly to sunlight. This one has uv protection. A good purchase for our needs.

Works better for individual with longer torso.
The tank is a bit long for my back so it caused my neck to hurt while looking down to spray. It has a lot of pressure with just two or three pumps. A fairly good unit. Make sure you make a slurry for any mixing of granules, water solubles etc. because it will get clogged in the line and lose pressure.

best backpack sprayer available
comfortable straps/ high spray volume can get the job done faster/ great up close or spraying longer distances. I have 2 Jacto HD400s for different applications. would never buy or use any of the other brands again that I used to have after being exposed to how well my Jacto works.

Will not maintain pressure
Similar to some of the other reviews, this sprayer stopped maintaining pressure after about 4 uses. You can pump for hours and get only a trickle from the hose. So disappointing , what a waste of money
