Ran prefect, easy to assemble!
I have to admit I was a bit skeptical. I was looking at a $2000 Stihl fogger then saw this one on Amazon. We have really bad mosquitos and are surrounded by woods. After assembly I mixed up the 2cycle gas/oil, primed the bulb 10 times, closed the choke and it started on the second pull with no carb Adjustments ( Wisconsin sea elevation). I let it idle for 20 -30 minutes to break in the engine. Now, I set the flow meter ( near the throttle trigger to "1") on the first test and it was prefect for 4 gallons covering 10,000 sq feet of bushes and trees. here's the challenge! The fogger only weighs 25lbs but with 4 gallons you're now at 60lbs!!! So put it on the back tail gate of a pickup or a folding table, sit on a stool, strap in, adjust straps ( while it's running) be careful standing up because the first few steps will be like a drunken sailor!!! It takes a bit to get your balance because it's very topheavy. It worked very good blasting a fog 20-30 feet deep into the woods. ( do not use gas containing ethanol, it will destroy the carb). It seems very well made and I'm happywith it.

It would be lighter on Mars
I have put off buying a real mosquito fogger for years. This year, I bought the bullet, placed it in my cart, and, on a whim, pressed "purchase." This year has been exceptionally bad due to mosquitoes. Seriously, I swore a gang of mosquitoes had tried to carry my poor cat away one afternoon. No lie.Well, once I put the fogger together, which was no issue, I armed myself with the best-rated mosquito spray and went to battle. Pew-pew-pew, red leader down. I took all of them out. I am now on my back patio writing this without the threat of life and limb from mosquito kamikazes.In all honesty, it has worked well. No issues. A previous review said it was hard to assemble, but I did not have that issue. If you have put together kids' toys around Christmas, you will have no issue here. One review stated that it was heavy. Well, uh, duh. Think about it. The base unit is 22 lbs, and then you add 4 gallons of spray, which would weigh another 33 or so lbs. Overall, this would be 55 lbs. Not horrible, but it would be troublesome for small-framed people. I found that proper adjustment of the straps and keeping the unit high on your back helped. But, shouldn't this be expected? Maybe on Mars, water is lighter due to the changes in gravity. I wish I had bought it 4 years ago when I originally picked it out. Don't waste time on smaller foggers/disinfectors.

Bad backs need not apply !!!
Works as advertised and looks to be good quality build - easy start and run . Only issue is the weight when filled with water - too heavy for me to use with my bad back . Ordered a mount to secure it to my cub cadet to use . The sprayer really makes treating the yard for insects faster then you could spray it with a sprayer . I’d like to see a version made specifically for mounting to a riding mower or atv .

Great fogger
So far so good. The other reviews are right. This is very heavy. I have to set it on a bench and the put it one. It’s top heavy and backward to put on normally. I’m 6-2 230 and lift weights all the time and I struggle with it. If your an older lady or gentlemen just be aware you will need help putting it on. The motor cranks easy.

You don't get what you see!
What you get is not what they display. The parts in the pictures look tough and ridged. What you get is cheap flimsy parts. You'll see this when you assemble, nothing looks like the picture in the installation guide. It does work well. Only used it once so far.

No bugs !
I bought this because of my remote summer camping spot in the woods ... Ticks , Deer flies , mosquitoes , Nats were unbearable.. with this unit I sprayed 50 lbs of the granular insecticide over my 1 acre of land then with the manual you change a few things to spray liquid !! It fogs amazingly 25-30 feet so I sprayed into the tree canopy and all around the ferns and under growth and around my motorhome and campfire sitting area ...Incredible NO BUGS

Use the right oil mixture
For the price is definitely worth it! When I got it, it was bogging a little bit, but I realized my gas mixture wasn't good. I used 93 octane with the Husqvarna 2 stroke oil and runs smooth!
