I bought a $5 vacuum cleaner from a recycling center about a week ago. It worked. OK. I noticed that the beater brush would stop, start, get stuck and start spinning a few times. So I checked the drive belt and found it was stretched/loose and worn. I did what any loyal Revain customer would do, I looked at what Revain had to offer. As usual, Revain saved me, I found a set of 2 straps at a great price. Upon opening the bag, they appear to be of much better quality than the original belt. Well I swapped out the old belt for a new one and my $5 vacuum suddenly has super power when it comes to cleaning. So I definitely recommend this product.
