Looks like the same set I bought from eBay a year ago. I used them for my Nexus One. They, for me, are horrible. They would "stick" to the screen when trying to scroll around. One of the tips popped off and almost gouged my screen.
Dry rubber on clean glass does not work well.
Today, I was looking for a charger and noticed the red cheap stylus in my drawer. I'll try it on my Xoom when I get home tonight and post back on how it feels in case someone is curious.
