Powerful blower
Size: Brushless Blower (4.0Ah)
I love this leaf blower. I have been using a corded blower for many years which tied me down to the length of the extension cord. I love the fact that I am not dragging an extension cord around, so I can use this in many more places on my 5 acres of property. It is not too heavy. I use it for cleaning the deck, for blowing leaves off the driveway, etc. I should have switched to cordless sooner. The battery lasts a long time before recharging. It is very powerful. ... show more

Blower does much better than expected
Size: Brushless Blower (4.0Ah)
I have a Greenworks weedeater and needed a new blower. After using a cheap battery powered blower that didn't have much of a charge or power. This blower has exceeded my expectations. Very powerful. Battery last quite a while unless you use the amped up speed. As far as weight goes, yes it is a little heavy because of the battery but not any heavier than a gas powered. Battery doesn't take oolong to charge either with a very nice feature on the battery where you push a button and it will light up a scale to let you know how much battery you have left. I will stick with Greenworks! ... show more

Nice Light Bower
Size: Brushless Blower (4.0Ah)
The blower performs well, is relatively light in weight and is powerful enough to do what we need done. It is a bit noisy, however. The only issue so far is with one dead LED charge indicator on the battery, but the battery seems to charge to capacity. Definitely a good secondary blower for larger lawns or incidental lawn cleanup. ... show more

A cost-effective alternative
Size: Brushless Blower (4.0Ah)
I wouldn't go so far as to describe it as having an "ultralight body" or "library-quiet operation," as advertised. Before deciding on this purchase, I researched comparables. Compared to the Toro 60V MAX 565 CFM brushless leaf blower, which is rated at 63 dB, my Greenworks 40V MAX 550 CFM brushless leaf blower is rated at 78 dB. Although the Toro has a lower decibel rating, it is heavier, weighing 9.7 lbs with its weaker 2.0Ah battery, while the Greenworks is lighter at 7.5 lbs with its 4.0Ah battery. A rating of 78 dB is far from "library quiet." In reality, a typical library measures around 40 dB, while 78 dB rivals the noise of a kitchen blender or a vacuum cleaner running right next to you. Additionally, my Greenworks 40V 4.0Ah battery pack offers a higher overall capacity and superior performance compared to the Toro 60V 2.0Ah battery. To accurately compare cordless tool batteries, you cannot simply consider volts or amp-hours (Ah) individually. Instead, you need to multiply these values to calculate the total watt-hours (Wh), which represents the actual "fuel tank" capacity of the battery: Toro 60V 2.0Ah battery: 60 volts × 2.0 Ah = 120 watt-hours (Wh) Greenworks 40V 4.0Ah battery: 40 volts × 4.0 Ah = 160 watt-hours (Wh) Therefore, the Greenworks battery pack delivers 33% more total stored energy than the Toro battery. In addition to providing longer runtimes, my 4.0Ah battery handles heavy-duty tasks much more effectively due to the configuration of its internal cells. Toro's 2.0Ah battery pack uses a single row of lithium-ion cells connected in series. When you activate the "Turbo" button on the blower, the motor demands a large surge of electrical current, placing significant stress on that single row of cells and causing the power to "droop" or fade under heavy load. In contrast, the Greenworks 40V 4.0Ah battery pack uses two rows of cells. When the Greenworks blower draws "Turbo" power, the battery distributes the electrical stress across twice as many cells, maintaining a fade-free peak velocity even when the battery is low. This design also helps keep the battery cooler, preventing overheating and premature shutdown. I highly recommend this Greenworks brushless leaf blower model. Keep your receipt for 3 year warranty. Contact Amazon if needed in first 30-days of purchase under Amazon's support link in your order. Thereafter, contact Greenworks. Hopefully you will never need. ... show more

Greenworks 40 volt blower.
Size: Brushless Blower (4.0Ah)
Blower is not that heavy with the 4 Ah battery. It's compact design is easy to maneuver in tight spaces, and has enough power to "dig" out leaves from around plants. Minimal assembly. Battery lasts a bit less on turbo of course. We will see about longevity when it is used more, but for now happy to have it! ... show more

Batteries are the "weakest link"
Size: Brushless Blower (4.0Ah)
I Live in Costa Rica and purchased some Greenworks items from Amazon and paid for them to be shipped here. I originally bought the Pole Saw and Hedge Trimmer along with the 16 inch String Trimmer. I got 2 batteries and 2 chargers with those setups. I also purchased an extra battery so I wouldn’t have to take so many charging breaks. Well, the Pole Saw failed after using 2 times, not even used enough to require a re-charge. In Costa Rica, when things break, it’s either fix them yourself or throw them away. So, I opened it up and found that a wire cam loose from the motor… fixed it and it worked for a short while longer, then died again. The hedge trimmer seems to work well still and the string trimmer has been very reliable. However, the batteries decided to discharge down to Zero when using and wouldn’t charge again. That left me with 40v equipment and no batteries. I ended up buying a blower with battery because it was almost as much to buy the battery alone. The Blower works great…. BUT, the battery decided to die while using the string trimmer and wont charge now. So, now I have the Broken Pole Saw, a working Hedge Trimmer, String Trimmer and Blower with no working batteries. None of these batteries were charged more than 5 times at most. Very Frustrating… It was great when the batteries worked (except the pole saw), but now I need to figure out if I want to risk buying more of these batteries or switch to a different brand and throw out all the equipment. ... show more
