Very pleased with the mower - quiet operation (only a third as loud as my old 2004 mower), cuts great, self-propelled is so good it will go faster than I can walk at full-speed! Key-start is awesome - no more shoulder cuff strains! Mulches very efficiently and bags with ease - the bag is a little small but the mower is able to very densely pack the bag so it doesn't have to be emptied very often. Key-start works great, gets 8-10 starts before needing to be recharged. As with the other lawn-boy's, you have to send off if you want a side-discharge chute, which others have complained about but I don't plan on using the side-discharge, just be aware if you plan on using that feature. Also, the mower takes the entire 20oz bottle of motor oil, just pour it in and go. Assembly took 10 minutes tops, just unfold the handle, put in fuel and oil, charge the battery, and go. A vast improvement over my old mower, and I'm looking forward to years of great use. Ordered on a Friday with super saver shipping, showed up the next Wednesday - how great is Amazon? The UPS guy wasn't too pleased about lugging a 90lb box but oh well :) You won't be disappointed with upgrading to this unit - I wondered if the key-start was worth $50 but I can easily say it's worth it - and even when the battery dies, the pull-string started on the first or second pull every time.
