Review on CyberTech Replacement iRobot Roomba 3 Armed Side Brushes for 500, 600, 700 Series (Excluding 645, 655, 675 & 670, 671, 690) by Andrew Smith

I bought a pack of three Roomba brushes in early December because I knew I would need them soon. I opened the package today and two of them are unusable as the plastic is bulged and won't fit in my vacuum. I tried to return the item and it says it can't be returned and see recommendations. There is a 30-day right of return. I understand the rules though. I think if you sell faulty products you should advocate for their replacement. Buy with care and be wary of return policies. waste of money
