By far the best lead blower I have ever owned! I was so done with the carbs in the two stroke ones gumming up I looked long and hard and stumbled across this. It has plenty of power and isn't very loud. It blows about as hard as my old two cycle hand held but no more mixing gas, burning fingers on exhaust, sore arms, and cleaning carbs! It's not very heavy and once you have it on your back it's a breeze. I wish I would have bought this 15 years ago. All the big name brands still use 2 cycle in their backpacks so I was a little apprehensive but those fears are long gone Sinex for the win!

I have actually put it to a true test, but after the easy assembly I did give it a test run. Started up very easily. Shoulder straps were easy enough to adjust and the blowing/air power seemed to be very strong and what you would expect from this type of blower. So far I’m very satisfied with the quality, results and purchase.

The product arrives quickly. The back is lighter than I expected. The instructions are easy to follow. It came with the proper oil, I added gas, primed, two pulls and it was running. It is quieter than I expected. The unit has good power for moving leaves. Good value.

I’ll be honest—this is my first time owning a backpack blower, and wow… I’m seriously impressed. First off, the fact that it’s a 4-cycle engine is a game changer. No more messing around with pre-mixed gas—just fill it up with non-ethanol fuel (I go with premium) and you’re good to go. Simple, clean, and hassle-free. Assembly was a breeze. The pre-measured oil in the little squirt bottle was such a thoughtful touch—it made setup foolproof. I even kept the bottle so I can nail the exact amount during future maintenance. I had seen a few complaints about the pull cord, but honestly, I don’t see that being an issue. There’s a built-in lip where you can brace your foot, which keeps the blower steady and makes starting it super easy. No awkward tug-of-war required. As for comfort—this thing delivers. The weight is well-balanced, and it feels great on your back. I used it across my entire 2-acre property and barely felt worn out… aside from realizing I might’ve hibernated a bit too hard over the winter 😄 Bottom line: this blower punches way above its price point. It performs just as well as the big-name brands without draining your wallet. If you’re on the fence, I’d say go for it—you won’t regret it.

The tool is well‑made, sturdy, and performs exactly as advertised. Great value for the price and definitely useful for anyone looking for a dependable option. feels durable, works smoothly, and is a good choice for anyone needing a reliable SENIX product.

I am very happy with this purchase. The price is well worth the purchase. I'm not a fan of 2 cycle gas mix.

Works very well, low vibration, much quieter than a 2-cycle. Don't have to mix oil and gas. I have a lot of very big trees, which the blower handles the large amount of leaves. One is a very large sycamore tree with large leaves, no problem for the blower. Very pleased

We have med.size property with only some trees and bushes, not need for big machine.4QL got enough power for what we need, Because is 4-cycle run quitter and cleaner. Very easy assembly, and start with ease. Thank you for great service.

Only used the unit a couple of times so far. Unboxed it and assembled it and it started first time. Used it a few times to move leaves out of my rock beds and it did the trick.

This 4-cycle blower is a major disappointment. While it looks good on paper, it is completely unreliable for actual yard work. It starts sputtering after only a few minutes of use and refuses to run smoothly once the engine is warm. If you shut it off, it won't restart, making it essentially useless for finishing a job. I expected much better performance for a 4-cycle machine.
