The chips themselves look pretty much like the same chip that is sold with the WPT logo. They're a standard plastic chip with a metal slug, but the inlays are of decent quality with a slightly rough surfaces that tends to add a little adhesion to the chip. This is the first time that I've seen them with a Bellagio logo, but I wouldn't expect them to be any different from the chips with the WPT logo. There's a review of the WPT chips at
http://www.pokerchipreviews.com/injection.html that might give you a general idea of what to expect.
UPDATE: Just found out that this particular set is being carried in some of Wal*Mart's Sam's Club warehouse stores for about $100. There's some question as to whether or not this version has a metal insert though (at least not one that responds to a magnet, and the cards included are rumored to be some sort of plastic. I have no other info and don't have a Sam's nearby.
