I've been really disappointed in their base layers, I've worn holes in mine in less than a season, nice and warm, but definitely not bifl. On the other hand I have Craft long underwear and Duofold items that are nearly 20 years old that are in better condition than any of my Smartwool pieces.

There are corded electric snowblowers out there but they are only powerful enough for single stage models. Dual stage requires more power than can be safely delivered from a 110v outlet. Hence the batteries on dual stage blowers. Not to mention that you need really high quality thick gauge extension cords to run even a single stage electric blower.
