It is very light and super quiet. Also, you don't have to breath in all the fumes like with the gas powered ones and much better for the environment. I live in Tahoe, so having a snowblower is a more of a requirement than a luxury. This is great, but does not compare to the power of a gas blower. You have to do a couple of passes, sometimes skimming the top and then coming back and digging in a bit. If you push too much it will get clogged and turn off.
I really did want to love this, but after using it just two times, it stopped working. I was able to return it and they shipped me a new one. However, this was in the middle of a snowstorm, so I had to shovel while the new one came. We are now getting another storm, so I took it out of the box this morning, and it seems as though they sent me a used one. It is all scratched and stained. The parts are loosely thrown in the box and nothing is wrapped. Let's see how long this one lasts.

Pros:
Light Weight
No fumes
Easy assembly
Easy on (Push button while holding handle)
Quiet

Cons:
Turns off when too much snow
Clogs easily
Does not throw snow very far
Battery runs out quickly (Extended battery purchase is essential)
Motor died after two uses

I purchased this to replace my older Greenworks corded 21" snowblower. It's much more convenint to use (probably much safer than draggiing multiple 120 volt power cord(s) around in wet snow). It seems to be just as, if not more, effective at removing & throwing snow as my corded unit. The chute is well-designed to prevent snow/ice from penetrating & inhibiting rotation. The chute rotation is fast, not precise.

For comparable power, the 80V system uses about half the current as 40V models, which means one-fourth the Joule power losses (greater efficiency). The bushless motor & 80V battery combo packs a good punch even in deeper, denser snow. I intentionally pushed this unit nearly to stalling a few times, but it always quickly recovered to full power.

The unit ran with no apparent power dropoff after removing over 500 sq feet of moderately dense snow over 8 inches deep. With a hot battery from my first torture-test, the charger initially flashed red (a source of panic & consternation among some), but I allowed the battery to cool a few minutes, and it calmly recharged to 81.5V in around 30 minutes. The dual white LED lights are effective, not just a gimmick. This may not be a throaty 28-inch, 3-stage, high-maintenance drift-buster, but for the price, its quiet performance is great insurance against cold-weather coronary failure, and its nearly zero-maintainence makes it a pleasure to both own & use. I wonder what Greenworks will do for an encore ?

I bought this blower in July when it was on sale. Wasn't sure how it will perform but my friend has a GreenWorks lawn mower and he loves it so I took a chance.

We had about 4" of snow last week and the blower went through it like a hot knife through butter. Admittedly the snow was of the light fluffy kind. Today we had about 2" of wet heavy snow, same thing. It worked flawlessly. I was wondering how long the battery would last. So I did my driveway and two of my neighbors as well as mine and my neighbors' sidewalk and a small patio. I and one of my neighbors have a 3 car driveway which is about 45 feet long. The other neighbor has a 2 car also 45 feet long. The battery didn't run out until I had about a 3 foot wide patch left, which I had to shovel by hand. Not too bad. I'm happy.

I don't think this blower will do as well in wet heavy snow above 6" but I live in a community which shovels my snow when it goes over 4". So for me this is perfect.

I bought this snowblower quite concerned about the mixed reviews. But I didn't really need the power of a gas-powered blower and didn't want to have to deal with the weight. I live in mega-snow country in Vermont but decided to take a chance, planning to use it mainly on the front walk, front porch and back deck (a local guy does our long driveway with his truck). I have to say that many of the reservations in previous reviews are correct - and at the same time, I'm reasonably satisfied.

GOOD: As everyone says, it's light - 30-something pounds. Makes it possible to regularly lug up the 6-foot steps onto my deck, then back down again to do the walk. It is definitely quiet, though I didn't really care about the noise level. And it's a cinch to use. The battery is easily charged and it starts instantly every time.
BAD: This is definitely a low-powered blower. When I first got it, a good foot of semi-frozen snow had built up. Rather than just plow through that much, you have to sort of take some off the top, then a little more, then a little more. Other reviews estimate that it can handle 4-6 inches. I'd say that's true of powdery snow. But when it comes to heavy, wet snow or semi-frozen snow, it can probably handle 4 inches or less at a time. Plus, the low power means you sometimes have to push. If you want effortless, go with a 100-pound self-propelled gas blower.
THE VERDICT: This blower is all about trade-offs. For me, light weight and ease of use were top priorities. It delivers beautifully and was the right choice for my needs. But to get that, you need to stay on top of a storm. If it's a good bit of snow, you will probably need to go out while it's still snowing and keep up with it. If the snow does get deeper than 4 inches or so, you will need multiple passes to get it all. And no, it doesn't scrape snow down to the ground or walkway. You'll still have a thin layer. But it will be easily walkable. I gave this 3 stars but that's kind of misleading. If it fits your needs, and you understand its limitations, I'd give it 4 or even 4 and a 1/2 stars. If it doesn't, 1 star! By the way, I bought an extra 2AH battery. One lasts a half-hour or so. Some reviewers say they bought the 4AH, which is too long for the protective cover to close, and they jury-rigged plastic and tape to protect the battery compartment. I wasn't comfortable doing that. But either way, one 2AH battery may not last through a big job. Having said that, it recharges quickly.

After several horrible, back-breaking winters, decided we'd had enough and it was time to get a machine. Could not face dealing with gas or a cord. Shopped around a bit but opted for this one because of the quick 30-minute charge (which is awesome!) First storm of the season dumped over two feet with even deeper drifts, decided not to try to tackle that with a 10-inch-deep machine. Next storm was a slushy mess of a foot. Was really pleased at how well this dealt with it. No, it couldn't handle the very bottom layer of an inch-or-so of icy mess, but that was easy to shovel after the machine cleared the bulk of it. A guy walking by said he had given up because his machine couldn't deal with any of it.
Next storm was a more conventional less-wet snow (6-8 inches) and it was a breeze to chug through. We're happy with the battery life, got the whole double-width triple-length driveway done without a recharge. Turning the chute isn't quite as smooth as we'd hope but it works fine. Only trouble assembling was with one screw on the handle that didn't want to align, but we managed. I have some trouble pushing the battery into the compartment because I am not strong.
