Like my Yeti's, one is 45 or 65ish other is 115 to 120ish, they keepshit cold for a long time, they're great to sit on or use as a table, hell you could put your caddi up on a couple of Yeti's instead of blocks, with added bonus being that they are certified Grizzly Bear Proof.

But....both are heavy and both look like they would hold more than they do.

Don't know about any of the knockoffs.
