SR 450
SR 450 is rated 4.3 out of 5 by 17.
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.

Rated 5 out of 5 by from Great for diy mosquito control It's a little heavy with a full tank though does a great job with mosquito control. This sprayer will pay for itself in one season of treating your outdoor space for mosquitos.

Rated 1 out of 5 by from Sr450 backpack mister This product has a defective tank. This tank will eventually leak. When I say leak I mean like a broken pipe, extremely bad. The chemical you put in the tank will leak all over your legs and lower bank. We bought 3 of them for our company and all 3 eventually leaks.

Rated 5 out of 5 by from Had a leak problem at the chemical tank from dealer but I was able to solve it. works good after I found a weeping leak. I think the dealer had installed the low volume filter that I ordered with it. It leaked a little at the tank connection. I removed the tank and cleaned up the gasket (it wasn't noticeably dirty) but when i reassembled it, the machine worked great.

Rated 5 out of 5 by from The best and most reliable mister/blower on the market. Stihl SR 450 is a beast period. It is great for large areas and extra large areas. If you aren't using this product you are selling yourself, your company, and your customers short. The Stihl SR 450 has more power to get way into wooded areas and up into trees and dense foliage. When full it can be a bit heavy, but the upside is you can get alot more area serviced. If you own a pest control company and this is not in your arsenal of tools. You are not on the cutting edge of premier service. Buy it now!

Rated 4 out of 5 by from works good but is too heavy and it lid is hard to get tight my unit does the job beautifully but is too top heavy when full. the lid is sometimes hard to get screwed down and leaks while in use. i'd like to see stihl engineer the spray tank to operate from below the blower utilizing a pump somehow.....

Rated 5 out of 5 by from Great for Mosquito Control This misting blower does it all. I have treated my yard once so far with Talstar P and I can go outside in the evening and not get bit at all! I know other reviews say the unit is heavy, but hey 4 gallons of water on your back and a backpack blower are not going to be the lightest thing to carry around. I recommend filling it up on a sturdy table or truck tailgate, and then slipping the straps on over your shoulders after you have started the unit. I can't wait to to use this for fertilization and weed control soon. This product is not cheap, but it will pay for itself this summer by not having to hire pest control to treat my yard for mosquitos. Make sure you use Stihl's Motomix for fuel on all of your Stihl products as this will extend the warranty. It has a 2 year shelf life too. Not bad!!

Rated 4 out of 5 by from Good product-needs some refinement. We bought this sprayer to control mosquitoes and biting flies. We have used it several times to mist concentrated garlic oil. Pro's- the machine appears well built, starts easily and blows the mist out a good distance. Con's- the machine is not inexpensive and the accessory pump and tubes to use it as a blower cost extra. This machine loaded with water has to be the heaviest Stihl makes but the harness is not as good a quality as comes standard with their BR600 blower. The supplied harness does not have a chest strap or the adjustable shoulder straps that I have seen on the BF600 blower. The weight and price of this machine justify the improved straps as well as the accessory waist belt to transfer some of the weight to your hips. I've ordered that for my machine but it has yet to arrive. I'd purchase it again but I'm already trying to figure out how to upgrade the straps.
