Rated 4.0 out of 5.0 by Pleasantly surprised Being a die-hard gas leaf blower user, I was reluctant to try the EGO blower. I didn't think it would push the leaves in my yard and expected to take it back to Home Depot straight away. I was "blown away" by how effective it moves leaves and yard clippings. The good and bad: Pros: lightweight, powerful, moves more leaves than my last gas blower!, good controls, good balance. Cons: short battery charge life, needs a reinforced exit tube for realistically rough yard work. Final word- These should ship standard with the 4Ah battery, Period. I'm not sure what the designers were thinking. I'm quite sure they don't have a "normal" sized test yard to work from or they would not stand having a 2Ah unit for their own personal use.

Rated 4.0 out of 5.0 by Good Battery Makes the 2.0 Amp battery I have obsolete, which is unfortunate because I really don't like buying a product only to have to upgrade later. Yes, i understand the technology is always improving, but this battery (and the 2.00 amp one before it) is overpriced. I like EGO, the products are very good, don't get me wrong, I will continue to but them, but how about some sort of a trade-in program (like a cell phone?) December 30, 2015

Rated 5.0 out of 5.0 by Great quick charge time Nice light weight unit, good amount of use on a charge November 9, 2015
Rated 4.0 out of 5.0 by Get more out of your cordless blower The bigger battery lets me get through clean-up of my large yard. The smaller battery that came with the blower only gave me around 20 minutes of clean-up time (front yard). I can now swap out to the larger battery that lets me complete the side and rear yard without running out of juice. The smaller battery completes its recharge before I finish the larger battery, so if I needed to keep working after exhausting the larger battery, I could immediately switch back to the smaller batter. This is a great product. The downside is that the larger battery is expensive at $200 and is heavy. You have definitely had a workout after lugging this beast around for 45 minutes. December 8, 2015
Rated 5.0 out of 5.0 by Very Nice! I was given the Ego Power Mower as a gift and love it. I like the fact it is light weight and compact. The longevity of the battery gives me enough time to take care of the entire lawn, which I questioned in the beginning. The reduction in noise level compared to a gas mower allows me to use it anytime of day and not disturb my neighbors. I think my favorite thing about this mower has to be the 'head lights'! that is the best invention ever. I have really enjoy mine and would highly recommend this product. It is not the mower for very large yards unless you have a back up battery, nor is it the mower for someone needing tall, thick brush cut down. However if you have an average lawn, its the perfect mower for you. September 10, 2015
Rated 5.0 out of 5.0 by Outstanding purchase I do a lot of yard work and this battery works in seveal of my tools and lasts long enough to get my work done without any down time. November 10, 2015
Rated 5.0 out of 5.0 by Very pleased! I started out purchasing the ego trimmer and were so impressed with the power of the unit and life of the battery, that I had to give the mower a shot. I was impressed by the two amp hour battery that came with the trimmer, but I'm really impressed with the larger battery that came with the mower! The battery life is phenomenal and the power that it delivers is unlike anything I've ever seen. They are quick charging and it keeps my mower running strong for almost an hour. Then, I can snap my smaller battery in the more and run for another 30 to 40 minutes! This is a great product and I would highly recommend it. August 3, 2015
