Great all the way around.
Great rock for a great price. I live out the way and there is almost nothing like this around me and what is within driving distance cost 3 times the price. 5 ⭐️s

Don’t expect to arrive in one piece
Unfortunately every single piece was broken in multiple fragments.

Great product, but comes broken
I love the rock shapes (or the shapes they were supposed to be) but it all came in pieces, every single piece was broken. So plan on buying epoxi to glue it back together yourself. They would have been great other than that. I’m a diy so i don’t mind putting it back together.

Everything was in pieces
The rocks all came nicely wrapped, but all but one was busted and broken. I bought the branching rock in order to have branches. Can't do that now..... Maybe I can glue them back together?

I really like it
The colors, the colors. Purple everywhere, in different shades and nice, big pieces. I have enough to do my 30 gallon and the10 gallon quarantine tank. We'll packed, we'll shipped.

You do not get what you pay for
We got all branches after buying the regular rocks. Will be returning, we expected to get regular rocks that are wet hence the name LIFE ROCK. Our rocks were bone dry which means they are not life rock. Very disappointed that I did not get what was pictured. If this were a cheaper price we would’ve brushed it off but for $95 I am not settling with what I did not order.

All stems
All stems, no rock! Most of the pieces were broken as well. I was able to build a “stem formation” but didn’t receive a whole rock. I’ll put up some pics as soon as my water clears up. The piece in the back right I bought at the fish store.

Life Rock
Pieces in tact look fantastic, although every piece had something broken from packaging or shipping. Some can be hidden in sand and others, not so much.
