Convenient & Quality
I like that in a pinch if I'm getting low on tubes and don't have time to travel nearby to get more, I can just order them online.  Also, it tends to be a large quantity for a fair price given the convenience.  They come sealed appropriately.  Periodically some of the tubes are crushed upon opening the box, but usually not so much that they're unusable, just gently smoothing them out with your finger does the trick.  It hasn't made me feel that this is a product to shy away from.  When actually smoking these, you get what you expect, no surprises.
