    5.0 out of 5 stars Works well. Backpack is the only way to go

    The sprayer works well and is simple to use

    Well built. Durable parts & materials. Works exactly as expected. While many use with weed killer, it also provides an efficient method for spraying plant growth fertilizers.

    5.0 out of 5 stars The pack is reasonably comfortable to wear

    A.H. · April 28, 2015

    I used this all last summer to spray fish and seaweed based fertilizer around my 2 acres of orchard and gardens. It works well for me. I bought a longer tube for the wand so I can reach higher in my trees. The pack is reasonably comfortable to wear, even when full because it is well balanced and the handle for the pressure pump is easy to access when walking. When spraying my trees I tend to lock the trigger in the ON position and use the pressure pump to maintain a constant pressure. I find it very easy to use.The only problems that I have had are that the soft plastic tube came loose from the main tank and the trigger sometimes doesn't work correctly when locked in the ON position for too long. The plastic tube coming loose caused my pants to get wet because the fluid started coming out through the bottom. It was an easy fix and just required adjusting the tension on the clamp holding it in place. I think it came loose partly because I had put too much pressure in the tank. I deal with the trigger problem by sometimes releasing the lock when walking around and it seems to be fine.Even with the small problems that I had I still love this unit and am glad I bought it. I would certainly buy it again if I needed a second pack.

    4.0 out of 5 stars A quality sprayer after Stihl backpack!!

    Only used one time but seems acceptable.Holds pressure and tip selection is a nice touch.Only complaint is the shipping box was very beat up by the shipping company but no damage to unit…just box that is worthless after unpacking b

    1.0 out of 5 stars Strict return policy, even though item was shipped damaged.

    d.g. · June 16, 2025

    Purchased two, one for house, one for farm. One worked perfectly, the other was broken (noticed a patch job on bottom of box after opening) and leaked from bottom without getting to the end of the hose. Contacted seller asking for replacement or parts to fix, told us we were past the 30-day return by one week. Even after pictures were sent clearly showing damage.

    M.S. · May 29, 2025

    The media could not be loaded. I used the item twice, always washed it out completely after use and for the 3rd time.e, I just had a constant stream of herbicide running down my lower back/shorts from the unit leaking from below, near the hose point. Awful but expensive product. Very disappointed.
