Pros: The product itself gets 4 stars. I've used 4 sets of these (400) already and only had 4 coasters. That's just a 1% failure rate, and for the price that's acceptable.

Cons: The only con is the packaging. The bubble paper had no air! Worse, the plastic wrapping was torn away and all 4 locking tabs which secure the plastic cover to the base were broken; ALL 4 !! At least the discs were still on the spindle so (hopefully) they aren't scratched. Time will tell.

Overall Review: Newegg needs to take an interest in the packaging of these items. I'm not the only one to complain. The discs themselves, however, have proven over time to be of very good quality.
