( NOTE - I added a few more Customer Images to the gallery for this product; many of them have additional notes included. )UPDATE - It's been a few weeks since my initial, glowing, 5-star review. (included below) Since then, I've had a chance to mow my entire yard again completely; I also loaned the mower to a friend to try and even mowed my neighbor's yard to try it out under various conditions. So far, I haven't found a single hidden flaw with this mower, yet I continue to be impressed by more features of the very thoughtful design.First of all, I finally tried out the grass catcher bag. I had SO underestimated how useful it is! It really should be called a vacuum bag; it puffs up like an old Hoover vacuum cleaner as the mower sucks up everything in its path. Using the bag instead of the mulching plug, the vacuum effect also makes the mower work like a Flow-Bee, sucking the blades of grass upright so the mower will cut them more precisely, and it also helps catch straggling blades of grass along the edges. Best of all, it completely eliminates the need for any sweeping (or dreadful leaf blowing) along walkways, streets, or driveways; the mower vacuums everything up, leaving the area perfectly clean and manicured, like the lawn just walked out of a barbershop!I was also surprised at how much the vacuum bag can hold; the mower chops up everything finely and blows it all to the back of the bag; it takes much longer than I expected to fill it up. The bag is remarkably simple to attach and remove from the mower and exceedingly easy to empty, it also easily unclips from the heavy steel frame so it can then be turned inside-out and rinsed clean.It's important to know that if you attempt to mow grass that is particularly wet, it may tend to accumulate around the blade. (as can happen with any mower!) This mower is normally very quiet; so if it seems to slow down or start to sound noisier than usual, stop and turn it over to see if there's an accumulation of grass around the blade. If so, simply remove it manually before proceeding.I discovered an additional benefit of the folding handle when attempting to mow under a tree with low hanging branches. When temporarily folded down, it becomes possible to mow beneath such obstacles. Larger mowers and/or mowers without easily folding handles could never do this! The manufacturer probably doesn't officially sanction using the mower this way, but if you're careful, it's a another wonderful feature!More and more, the benefit of the smaller size and light weight of this mower becomes apparent. With the cutting height shifted into high, the little mower gobbles up weeds and even moderate brush as it maneuvers in and around, over and under, various obstacles and edgings. The medium setting delivers a beautiful cut for most of my yard, but then you can tailor it down like a "bald-fade" to achieve a tightly cropped putting green look.As I gained more experience with the comfortable, well-balanced "feel" of this mower, and the way it's so easy to adjust the cutting height for a precision cut, it began to remind me of the Andis Master Hair Clipper I bought not too long ago. Arguably the most respected hair clipper in its class, the truly beloved Andis Master is famous for delivering a very precise cut, and for having a beautifully balanced feeling that is delightful to use. (comparing a hair grooming product with a lawn grooming product makes sense, doesn't it?)---------------------------------ORIGINAL REVIEW:I'm very pleased with this Greenworks corded electric mower. The 16-inch cutting width is slightly narrower than "full sized" mowers; if you're looking to cut a vast expanse of lawn as quickly as possible, then choose a larger product instead of this model.PROS:1- Smaller size and weight make the mower very comfortable to use, carry and store. Fits through narrower areas and around obstacles easier than larger mowers.2- Quieter and less vibration than other electric mowers. (MUCH quieter than gas powered!)3- Well-balanced handle has a soft padded grip, is height adjustable, and folds down instantly for storage.4- Power switch requires two hands to start for extra safety, but then holding anywhere along the handlebar will keep it running.5- Excellent height adjustment mechanism; large "gear shift style" control on top of mower moves smoothly and easily locks into the desired position.IMPORTANT: Move the control to its highest setting when you first start out; adjust one-step-a-time lower until you reach the desired cut.6- No assembly required, boxed with no superfluous packaging.7- Thoughtfully designed and solidly built. Compared to other brands of electric mowers, this guy is and excellent value; I'm impressed!CONS: (considerations, actually)1- Smaller than larger mowers, will take more walking to mow large areas.2- Grass catcher bag has limited capacity; when using that feature, the bag will require more frequent emptying. (but it'll be easier to do)3- Needs electricity and an extension cord long enough to reach all areas to be mowed. (an otherwise identical Greenworks mower is available in a battery-powered model #25242, priced a couple hundred dollars more)MORE: For a few more details, please see the Customer Images I posted on the product page, noting some of the mower's details before and after I used it for the first time.
