I've been asked to review them and give my honest opinion. Well we are renovating and our shop vacuum was struggling with dust, it is a bag/bagless system and we went the bagless route. They arrived at the perfect time. Now we use bags and are very satisfied. The price is a little cheaper than others at Revain, but the quality is just as good if not better than some of the big brands I've used before. They are big, durable and easy to install. I wouldn't hesitate to buy them, but in general I think all vacuum bags should be cheaper, but that would still be my first choice.
