Rated 5 out of 5 by Great product, very easy to use I have over a hundred rose bushes. They have to be sprayed with fungicide at least every two weeks. I grew out of a 2 gallon sprayer and didn't want a battery pack one, too heavy, plus I have a very sloped yard and need to go up and down stairs, so a wheeled one wasn't practical.The Stilh was a great choice. It held over 4 gallons which was nice, it is lightweight, easy to fill and with the extended wand, did a great job getting into all the spots I needed it do, including climbing roses. I am only 5 feet tall, yet even with the backpack full, I found it easy to use and control (just don't bend down!) To get it on, I put the sprayer on a lawn chair, and then fill it. I then sit in the chair and put the straps on and stand up. Works great. It's not that heavy, and I consider my spraying time a 'weight bearing workout'. The pumping is a good exercise for my left arm. I love the freedom to walk around with the sprayer up and down hills without dragging or lifting anything.I did have to repair the hose once, and replace some o-rings, but otherwise it worked great for 7 years. I am now having some issues with the pressure, and since this unit is so old, I will likely purchase a new one. Much more reliable than other sprayers I have used which most of the time didn't last 1-2 years. July 26, 2014
Rated 5 out of 5 by Great Product Overall this was an excellent investment. All back pack sprayers most likely have the same difficultly of mounting after filled. It definitely needs to be at a height that can be put on while standing. However, I may be using the wrong technique. July 17, 2014
Rated 2 out of 5 by breaks down after about a year After about a year the shoulder straps broke and the tank pulled loose from the frame spilling weed killer all over the grass. The pump also started leaking from the top seal. Not a good choice. July 8, 2014
Rated 2 out of 5 by Too Uncomfortable and Requires Too Frequent Pumping and... As someone else said, I own (homeowner) many Stihl products, but this one just doesn't cut it. It is heavy with that heavy metal pump arm, and puts too much pressure on your back (most if not all others' backpack sprayers have a CURVED section that spreads the weight more evenly around your spinal area). Also, the wand is too flexible and you have to keep pumping to maintain a fairly decent pressure flow. It comes with only a single (brass) nozzle, which doesn't give too fine a spray-a little too course for my taste; many competitors provide 3 or 4 nozzles for different spray patterns, at no additional charge. It has a wide lid, which I think is its only plus. It is a fair traded item and the (un-negotiable) price is higher than almost all others. Pass on it. June 24, 2014
Rated 5 out of 5 by all around efficient I love this sprayer. It keeps the preasure. Balanced very well. Easy to use. The price was a bargain when you consider the quality of this and all Sthil products. I love the fact they are easy to use for women, teens etc. With or without coupons it is hands down a great value. May 9, 2014
Rated 2 out of 5 There has to be something better I'm a Stihl fan and don't use my equipment commercially, just to maintain my own yard, etc. I'm on my second SG20 sprayer. The first sprayer's tank split where it was unusually thin at the bottom. The hoses on both sprayers dry rotted in about a year. I only use my sprayer a few times each year, and store it empty and cleaned each time. I store it inside a barn. I last used my sprayer about a month ago and and the pump has now stopped pumping. I own half a dozen pieces of stihl equipment and the sprayer certainly isn't the same quality as all my other equipment. August 29, 2013
Rated 5 out of 5 by 5 years old work normal I have had my sprayer five years and it doesn't do anything wrong. My first repair was a new hose after the other finally dried out. Getting ready to buy another for a friend. Great value. August 17, 2013
Rated 3 out of 5 by Nice, but leaks Have several of these, for work and home. Light duty on all. Works well.The fitting need to be constantly tightened or it will leak. The one for home use leaks from the bottom fitting on tank, can't tighten that. New so took it back but still waiting for it to be repaired.Am going to track down a powered sprayer for treating for mosquitoes. August 15, 2013
