    • Nice but…
Looked nice but was missing the spray wand. Had to return it unused. BTW I wrote on the box the missing part so hope it doesn’t get sold to you!?

    • Good looking unit, works well.
Quality built, solid feel, easy to use, what more is there to say!? If you have a big garden or yard, this is for you, or else you get one of those chintzy little ones and then you'll have to measure and refill. Every time you do that, you risk spilling or contamination through skin absorption. Spend a couple of bucks more and get a decent unit like this one. ... show more

    • This works well but the straps are a pain
The unit worked on a 1/4 acre spraying job but when it is full the straps dug in a little. For the homeowner this is tolerable but I wouldn't want to use it everyday without modifying the straps. I bought it for limited use and for that it was fine. I see this being used in the future more than I thought. ... show more

    • Good Overall Item
Solid Product and sprays well. It is a little tippy when set on the floor and has some balance issues especially when empty. The handle doesn't have a real smooth feeling pumping action to it... its hard to tell sometimes if its working but it is. These are relatively minor issues and overall it carrys a lot of weight in product and sprays it out quickly or slowly depending on your preference. ... show more

This backpack sprayer sure beats the hell out of my one gallon for exterior spraying. extremely fast volume output so you can get the job done fast. very accurate, sprays how and where you want it to spray. down sides; wand leaks a little if some fluid is left in tank, even if set to lock, 2; poly wand warps if left in mild heat for a short period of time. over all well worth the money save your self the hassle of mixing one gallon at a time. (so far I've put 3 full tanks in it no problems besides what described) ... show more

    • save your money and buy soming else
I was after a high quality backpack sprayer that would last. This was recommended to me as the best and was told I should pay the extra for the diaphragm pump. I put 6 tanks of spray through in 2 days of using it before the diaphragm pump started leaking. I rinsed it very well following the instructions after using it. I called up the distributor in Australia and was told the pump was not covered by warranty and a replacement pump would cost 70% of the price of the unit. No sorry and no explanation why a unit described as high quality would fail after minimal use. Waste of money and of my time!!!!! ... show more
