I always find Staples stickies to be less sticky then 3M and fall off walls and dusty white boards. Also they are called bright colors but I find the colors muted and it is hard to tell the difference between the yellow and green.
My daughter is a teacher. Every year I help stock her classroom with supplies. The teachers use a lot of sticky notes so I'm always looking for a good deal on a good product. This is the product -- good product good price and the kids like the bright colors!
I work in a small fast paced office with a staff of approximately fourteen. I implemented a colored coded scheme to identify work from each department. Every department uses a differnt color stickie making it easy to to recognize at a glance where work orginated from at the close of the businees day.
