Item is fine and I'm going to keep it. However, I'm frustrated that UNS charges so much for a simple mass produced rock mold. It's not "hand crafted" by any means. It's a lightweight, simple molded resin that probably costs pennies on the dollar to produce. The listed dimensions are not entirely accurate so here is what they actually are - 14.75" L x 6.2" H x 7.25" D All in all, it's cool looking if you have the money to spend. Otherwise I'd recommend real rock where you could get at least 10-20lbs for the same price or less than a 2.5lbs mold. I got it for an ADA Paludarium which this rock is suited perfectly for. NOTE: The inside of this is hallow. If you are using it in an aquarium, make sure there are no openings at the bottom that would allow a creature to swim or crawl into the hallow underside or they could become trapped and die.
