What Customers Are Saying
Customers overwhelmingly praise this backpack blower for its exceptional power, comfort, and ease of use. Most highlight its ability to handle heavy leaf loads, wet leaves, and dense tree canopies with strong airflow. The 4-cycle engine eliminates fuel mixing, and reviewers consistently commend the comfortable, adjustable straps, lightweight design, and easy-start mechanism that reduce fatigue during extended use. However, some customers report fuel leakage issues with tank caps and fuel lines. Despite these concerns, most find the blower highly effective and user-friendly.

Would Not RecommendStarted up, after fairly easy assembly. Then the whole time it was running it spewed gas down my legs. Not going to fool with a tool that was junk from the start. It’s going back having only used it one time. Really disappointed that I’ll have to revert back to a 2 stroke engine.

$250 Paperweight
Would Not RecommendReally wanted this to work out; I like the 4-cycle engines so much better than 2-stroke. Assembly was straightforward. Filled up with oil and gas and fired it up. Started on the third pull. Ran for about 12 seconds and then refused to run any more. At some point while trying to get it to run I noticed that it also was leaking fuel. Drained the remaking gas and the oil and returned to the store.

Blower Has Design Problem
Would Not RecommendThe blower leaked gasoline from the top of the tank, due to the rubber grommet that holds the fuel lines coming off. Fuel spilled out and leaked, including some on me. The blower itself worked well. I had read about this problem on another review, but hoped that it had been fixed. It had not. I returned the blower for a refund and got another brand.

Great Buy
Would RecommendI was searching for a 4 stroke leaf blower that didn't require mixing gas and oil. This blower is perfect. The price is nearly half the cost of the Stihl blower. The reviews are spot on. It's easy to start and has all the power needed to blow piles of leaves, pine straw, grass, everything.
Excellent features like no gas and oil mix needed.
Would RecommendUsed it for the first time and I love it way better than the hand held blower. It has way more power which took me way less time to finish my yard.

This Machine Blows (away the competition)
Would RecommendWas initially reluctant as has never heard of the brand. But as company is based in Vermont, decided to give it a go. Would not have to go far to return, versus a trip to South Korea or China. Easy to read instructions, easy to assemble, and best of all, started on second pull!! Was "advertised" to weigh 29lbs, but the unit is less than 20lbs and operates quietly, with no vibration and very powerful. I especially like the 4cyl engine; no mixing of fuel and oil and the price point puts it far ahe...
