After buying some tape from another supplier for more money, and having it be unusable because it would not stay stuck to the boxes, this was a pleasant surprise from ***********. It was definitely higher quality than the other tape and stayed stuck like it's supposed to. It's nearly as good as the XX tape that I used to use which got too expensive on me. I cannot say what the tape is like from other suppliers of this XXXXXX item, but the Tuf Tape supplied by ************ is a winner. Hopefully it will remain consistently good as I buy more in the future. And they shipped it pretty quick too!
UPDATE 2/8/12: When I came back to order again, I saw that *********** was not the default vendor for the item anymore, so I made sure to choose them for this item even though they were a few cents higher in price. When I got the item this time, it was not the Tuf Tape as it had been last time. Instead it was a private label with *************** imprinted on the rolls. This made me very nervous about whether the tape would be good or not. But not to worry--when I tested it out, it worked just fine. So my recommendation of the ************* tape continues to stand.
