[Q]: Being a contractor for 25 years I know how to calibrate a stud sensor... this is the biggest piece of junk I’ve ever bought!!! I wished I could get my money back!!!
[A]: negative


[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


[Q]: Big waste of money. I have one of those offending front load LG wash machines with all the rubber in the front. Mold growing "greenhouse" with these machines. Thought this would help. Not a speck of difference. And it didn't clean any better after the 3rd consecutive cycle. Thank goodness this was cheap.

negative
