Great, need another one

Spraying herbicide

I’m a professional gardener. So I purchased one these last year for £86 A year later, for some reason it’s jumped nearly £50’in price. But they’re better quality than the cheap £20-£30 ones I’ve been using over the past years. They only seem to last a year or so before corroding or leaking.? So they’re a good well built quality knapsack. The only problems I had with the last one I bought was that there was a stupid plastic clip that held the piping from the knapsack to the lance. It’s a poor design that caused a small leak. I overcame this by removing it and replacing it with a jubilee clip. Problem Solved for the sake of a few pennies. This one had the same stupid plastic clip that will need to be changed. The only other problem I had with the previous knapsack was the poor design of the clips that held the shoulder straps on at the bottom to the metal stand. They occasionally came off due to the clip design. This new one looks as if it’s even worse. They’ve done away with a locking loop. And replaced it with just a clip that in no way locks on. It just doesn’t feel like it’s meant to be connected to the steel base stand. And that it will be forever falling off. It just feels like they’ve had a good design, messed with it. And actually produced a worse product for and charging us an extra £50 for the hassle. I’ve not used it yet, as it was bought to use selective weedkiller on lawns. But any problems, I’ll update the review

Great value, sturdy construction:)

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.

Very happy with this sprayer. Works great. Holds a lot of chemical to spray, wand sprays great and easy on the back. Definitely recommend!

Good sprayer

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.
