This is a nice leaf blower great value, it’s light weight and easy to use. Used a few weeks and it starts every time second pull doesn’t use much gas either. It does vibrate a bit but not bad. One thing people should know is that in order to make them last is to use non ethanol gas (usually found near a boat launch, marina etc) don’t have mess with stabil I use that gas in all my lawn tools and have no problems with gummed up varnished carburators. Even after 2 years. Overall this little blower is powerful and I think a great value for the money! $124 Update Dec 2021, this blower still starts every time, change the oil ones maybe twice a year and it keeps going. Only thing I fixed was that the blower pipe came loose, really sucks when your on a roof and it falls off… I just added a hose clamp. Update January 2024, still starts up every time, I checked the valve lash and found that the rockers don’t get much oil, it might have been low on oil, it’s hard to gauge. Valve lash was good, not that I could find a spec anywhere. There was a lash so it will not burn the valves. Update July 2025, Still starting up very easy, not much to report other than that it’s still a great little blower!

Iv owned this unit for about 3 months now starts on choke first pull then quickly give it throttle and the choke automatically turns off and keeps on running no second pull required. Iv been using pump gas 87 octane non ethanol treated with star-tron as I do with all my small engines and it continues to start and run well. Has a nice metal washable air filter Wich like, it's light weight and fairly quiet Wich is nice. Saw some reviews complaining the handle is weak and flimsy but it's not it's rubber mounted to reduce vibration so it flexes a little but still solid. Overall my only dislike is it's slightly underpowered compared to similar 2 stroke handhelds like the echo or Stihl but still does fine for the majority of needs like blowing off grass clippings ECT. I use these alot to dry my cars after washing and it takes a little longer with this one but less noise so it's a gain/loose situation vs the two strokes Wich I love but this is a nice change to use when I don't want to make as much noise. Overall I like it and would buy again if it lasts for a few years. Change the oil often on these as they don't hold much and using the choke to start can dilute the oil with gasoline overtime.

This blower starts easy and would be great except you can only get about 3/4th throttle out of it without it stalling so it is very weak and the carb is not adjustable. Amazon says it is not eligible (hazardous material) for return only repair (only had it two weeks) and who wants to mess with that headache?? I'll be purchasing something from a brick and mortor store to replace it and this company goes on the "never buy from again list"...

I contacted the company. I explained my problem. They told me the blower had a 3-year manufacturer's warranty. They asked me to send them a short video of the problem and proof of purchase through amazon. They are sending me a new one. Very reputable company! Worked great for a year. Never used much, only occasionally on weekends during the summer at our seasonal camping site. I even made sure I drained all the gas out of the tank and ran it until it stalled so there was no gas left in the carburetor before I put it away for the winter. Tried using it this year won't Prime up with fuel when pressing the little button and only runs for a few seconds before stalling out obviously from not getting fuel. Loved it at first but unfortunately very disappointed now! I'm going to call the company to see if there's anything they can do for me. Hopefully I'll be updating this review if they do the right thing.

I purchased this blower back in the fall of 2019. It appealed to me because of the 4 cycle engine. Honestly, it’s great to see some outdoor tools going to the 4 cycle route. PROS: When I first bought the blower, I added an hour meter to track it’s progress. I’m currently at 20+ hours already. - it’s lightweight, definitely heavier than a 2 cycle blower but still manageable. - it’s much quieter than your typical 2 cycle. It states 69 decibels; I would agree on that. - no mix involved. - small but powerful motor: it’s responsive - I’ve read some of the reviews regarding starting; honestly, I’ve never encountered an issue with starting. Generally it starts on the 3-4 pull; this after making sure you prime the carburetor. CONS: It does not have a locking throttle, you have to hold down the trigger - the gas tank is on the smaller side. It goes a bit quick. FINAL WORDS: my unit came with a high idle. I lowered the idle a lot. This also helped with fuel consumption so it is not running at a high rpm on idle. This blower is not a commercial unit however, I own 3 acres of woods and ran this all day without any incident. I own Stihl backpacks and use the blowers a lot. I’m no stranger to outdoor power equipment. But with that said, I’m happy with the overall construction of the unit. Best bet is using non- ethanol gas for longevity. Run the unit dry if it will be put away for a while. It’s not the most powerful of unit but it is handy and tackles what i need. If you have a smaller property, I’d recommend. To date, it has been trouble free. I’m now considering the Senix Gas trimmer Update: well it’s been a while after purchasing this unit. I’ve put it to work quite a bit but not heavily. I added an hour meter when I bought it and it is now hovering around 30-40 hours of use. Sadly it’s giving me hard time to start and run this season. It’s been stored properly, always use Stabil in the gas, well kept but this season she doesn’t want to run. I’ve had the carb off a few times now, cleaned, spark plug cleaned but no go. Runs only on choke but will not rev. I’m not giving up just yet
