I liked the caviar from Releaf... did a review on it if you guys are curious: MMJinColorado.com - Informal Review of Sour Diesel 'Caviar' | MMJ in Colorado

The taste was pretty great IMO, it tasted like the Sour Diesel nug inside it only a little stronger and hashier due to all the THC content poured over it. The tiny less-than-1/4 g piece I had was good for 5 smoke sessions (3-4 hits each) and I was blazed off my ass afterwards.

The price is still kinda crazy, but I could see a gram lasting at least as long as a gram of hash, probably longer. It's a nice treat... like someone else said, it's a tolerance killer -- so if you're feeling underwhelmed by your stash, it's a good way to wake yourself up.
