It is all about quality, and bubblebags are the best quality out there. I have been making bubble with the same pair of bags for almost 10 years, the rest of these companies have not even been around half that time. Bubblebags have grwat customer service, not one of those other companies have a forum or a 1800 # if you need help. to me it is a no brainer. B Bags all the way.
