Pretty easy to assemble. Perhaps 20 minutes or so in total. Gets VERY warm! Perfect for our northern Michigan winters. Once I used this, I quickly regretted not getting this kit when the snow blower was new. Highly recommend it. One suggestion with respect
to drilling the hole in the snow blower panel. The panel has a thin laminate across the top that is really not visible, but the 1/2" drill caused the laminate to separate and lift up from the panel around the area where the drill bit was working. The gap this
created between the laminate and the panel quickly filled up with metal shavings that I had to clean out so the washer that fits around the toggle switch would lay flat when installed. There is still a quarter size area of separated laminate that is visible
around the washer and is a bit unsightly. I would suggest cutting a small circle through the laminate with a razor knife around and slightly larger than the 1/2" drill bit so that the laminate within the cut separates cleanly without gathering shavings and
any separation is limited to that small area within the cut.
