“There are a few pieces in this set that I think are pretty neat, and the set's moderate price tag make them a fun thing to pick up. While I don't expect fans to be doing cartwheels down the street to pick this one up, I do think the bashing was a bit premature, my own... More included. I think opinion initially was cruel to the Power Miners theme, but history will bode well for it.”
Brickipedia
“The Crystal King has grabbing claws and crystallized teeth. His body is glowing with crystals, caused by devouring many crystals in the past, and he can fit a whole Power Miner in his mouth. Because this set features no vehicle of the Power Miners, it has no set number on... More any bricks, unlike every other Power Miners set (excluding the promotions: 8907 and 8908).”
