I purchased a closeout SJ615E bundle at Walmart for keeping my deck clear and finally tried it out on 2" of crisp powder at 5 degrees this morning. Worked so well on the deck that I used it on the walkways, too! Didn't bother with the drive, since there's big snow on the way and I have a new Honda HSS1332ATD to try out on that in a day or so, apparently. The SnowJoe is back on the deck awaiting more action there.
