I have only used this once but it is by far the best sprayer I have come across. Much better than the usual garden centre ones. Easy to pressurise and good spray pattern which was consistent. Wish I had bought one years ago despite the price.

Brilliant! Like all Stihl products, over-engineered and a joy to use. Soooo much better than regular sprayers. Pressure easily regulated and it sprays our box hedging in minutes rather than hours. Well worth the money.

Excellent sprayer, have had other manufacturers sprayers previously and this is by far the best. Well designed and easy to assemble. Operation is very smooth, and the pressure gauge is very useful, all sit comfortably on the back when carrying.
The process in ordering with Radmore and Tucker to delivery extremely efficient and prompt.

Really good quality spray tank for the price can’t fault it by far best spray tank I bought!

Fitting the hose at the bottom of the tank was a challenge, but this is easily the best quality sprayer I have bought. It’s easy to use, and as others have said the spray pattern is excellent and the pressure gauge a bonus.

First class piece of equipment, well built and robust. Chose this brand as their chain saws are the best in the world and this sprayer proves their reputation for quality.
As with all sprayers of this capacity its quite heavy to hoist onto your shoulders if filled to capacity and ideally best sat on something like a stool to elevate it before fitting to your shoulders.
The pressure gauge is very useful and spray angle works well. I would recommend this sprayer to anyone, if they are happy that the volume suits their needs.
If I had any negatives it would be that the holder for the spray lance is not brilliant but this does not detract from its quality overall.

I haven’t used the sprayer yet, but Radmore and Tuckers price was good and very quick delivery. Very pleased.

A great spray pump backpack, though, it still takes a long time, to dispense a lot of liquid/feed onto your lawn, etc.
The backpack spray itself is very well made, is comfortable when full too, and works so, so much better than smaller, bottled pump spray bottles.
in terms of Radmore tucker, they did a great job, order and delivered as expected, next day, really great service, thank you.

Tough, durable, simple to use and clean out. Handy pressure gauge to allow you to keep an eye on it.

Although this Stihl is a first class knapsack, it’s tough and durable, and is comfortable on your back and shoulders.
The lance holder could be deeper to stop the lance from falling out of the bottom holder while carrying the knapsack.
The pressure handle is brilliant because it pressurising both when you raise and lower the handle, and the pressure holds much longer.
The spray is very fine and covers extremely well.
The main negative for me is that the bottom of the plastic tank itself is much wider than the shoulders of the tank, making it very heavy when full to capacity.
I’m really pleased with it. It’s so much better thank my old 15 litre knapsack.
Although a friend bought this knapsack on my behalf, I can recommend Radmore and Tucker for their very efficient service and speedy delivery which is second to none.

Should have bought a Sthil years ago.
Gauge is a handy add on, where the lance sits is great, even the little lock to stop spillages is good.
Buy cheap but twice
