I used the blue sticky tack Freshman year for a lot of posters and never once had a problem. This semester, using the white scotch stuff, my posters fall on my head in the middle of the night...often multiple times. I'm a bit fed up with that. The quality of this tack is so atrocious compared to the blue putty which is the same price! I just popped on here to get myself some blue putty, saw this product for sale, felt an intense rage build in me (this was a night when my poster fell on my head multiple times), and had to write a review. So, I'm off to buy some good tack. (Hint, not this stuff)
