I did a lot of research before making a snow boot purchase, hemming and hawing due to the expensive nature of waterproof boots.  These were worth it. This past weekend was the first weekend I had these boots, and I gave them a serious snowstorm workout. I've walked over three urban miles in deep snow/ slush/ ice in them, sat in a restaurant wearing them for a few hours (twice) and wore them to a concert.  Drove in them.  Walked around Home Depot & the grocery store for 2 + hrs in them.  I mean, really they barely left my feet for 3 days.
PROS:
- comfortable
- dry
- warm
- love the fitted top to prevent snow sliding into the boot top (looking at you, rain boots)
- kinda cute in a storm trooper riding boot kinda way; look great with jeans or tights tucked in
CONS:
- a bit bulky in the ankle makes it harder but not impossible to drive
- rubbed a bit on one heel the first day.  Heel recovered quickly.
- when i got them, they were a bit greasy on the plastic boot
- feel heavy after sitting for long periods of time

Overall, I think these are a great boots that will work in spring rain as well as winter snowstorms. And once you get over the shiny plastic shock, cute enough to wear into the office, bar, or to run errands without looking like a little kid (weird pink and blue patterns), kid of the 80s (duck boots) or 2007 leftovers (aka boots with the fur).
