Rated 5 out of 5 by from Machine is a beast! I bought my Stihl back in the spring of 2014 when I opened my company and I can tell you now finishing up my 4th mosquito season and servicing over 90 customers a month that this machine is practically bullet proof. Throttled out on an acre of property with nothing but English ivy it works like a champ. Use Stihl 2 cycle oil as recommended and change the plug every season and you'll be very happy. The diffuser design on the end could use some reworking, but a small tent bungee strap rigging on its fine.

Rated 5 out of 5 by from Awesome unit I bought one for mosquito control for my small Landscape Company yes it is heavy. However it does the job it starts up every time I have used mine all summer now and I have never had any significant issues.

Rated 1 out of 5 by from Leaks. Wow. Stihl. Brand new. 5th backpack I've used from Stihl. All the others worked flawlessly. This one blows. Motor is very strong but the water continues to leak in spite of turning off the nozzle. There needs to be a shutoff inside the tank. This would help in two ways: 1 you wouldn't have to premix chemicals in a secondary container 2 it would never leak. You're better than this Stihl.

Rated 5 out of 5 by from Bought mine a couple months ago Haven't had any issues yet, it appears heavy at first, but you have the tank on your back, so it'll lighten as the product disperses.

Rated 4 out of 5 by from Great product - except overall weight can post repetitive use issues. Wish Stihl would utilize a backpackers shoulder harness and restraint system to properly strap the unit to ones body and eliminate unit migration anytime the operator leans to one side or another, and then having to deal with sloshing liquid transfer. A proper backpackers harness would improve this unit 10fold!

Rated 5 out of 5 by from Great Performing Sprayer I purchased this sprayer to apply pest control in my yard. The SR450 is powerful enough to get high into my privacy hedges and trees. It also works great to move leave when I just need a reliable, powerful backpack blower.

Rated 5 out of 5 by from Great product Love the product and works as expected. The diffusers on the end of the wand do not attach very securely. It would be nice if they had a better locking mechanism. The price is a bit high also, but it is a good product.
