[Q]: These worked out wonderfully for our event! I have to admit, I was skeptical at first, but they were soooo much better than I could have imagined! And a great price!
[A]: positive

[Q]: This brush is a snow and ice BEAST! It is, perhaps, the most solidly built brush and scraper, with easy extension and easy rotation of the brush to change its angle relative to the shaft. As it is a new purchase for me, I'll have to update this later in the snow season. And, frankly, I'm hoping that I won't need it again this season. But I am prepared! Fast shipping, and excellent follow-up by the sender. highly recommended.
[A]: positive
