I have a version of this shovel that I purchased about 3-5 years ago. The plastic bottom of it was getting pretty worn, so I bought a new one for this winter. The design combines the best of ergonomics & flexibility. The two little knobbies that hold the flex handle in place snapped in the sub-zero temperatures this morning, leaving me with a new, broken shovel with only 5 shoveling days in. The snow wasn't even heavy or packed. So now I will go back to using my old, worn shovel of the same model & try to figure out if I can switch parts on the two.
Pros: Functionality, ergonomic
Cons: Not Durable, knobs on secondary handle can break in cold
