Are there stakes that hold it in place? Assuming it is light weight and could blow away?

They look so light, but believe it or not, they are heavy enough that they don't blow away. The funny part is that they look like the real thing. Hard to tell them apart from real rocks.

Can the back be cut out? If so, with what tool?

This product can be carefully cut using a power saw

Is it waterproof so electrical equipment wont get wet underneath?

Not sure about waterproof. I keep mine running 24/7. I bough a fake rock to hide and cover it. I also put three bricks under it to keep it off of the ground. When it gets below freezing, the unit runs, but the air lines freeze up and no air gets to the stones. I pull it out of the pond and let the lines thaw out inside the house. The stones can be cleaned off with mild soap and water. You should get some extra air line and swap out with the old lines.

Is this hallow underneath? How big is the opening?

Hi there, I just measured one. It is almost as big inside as outside. On the long edge it is 10" across and at the deepest spot the hole inside the rock is about 5" deep. I have pictures i can send if you text your email address. Sincerely, Nate "at" Practical Garden Ponds 484-356-5351

Looks realistic.

Excellent looks. Very realistic. I'm very happy with the quality. Great value for the money. I used a can of spray foam to custom fit it around the clean-out. It fits so tight it won't move around or get kicked over by the deer.

A very realistic stone.

This is the second one I’ve gotten. They are very realistic and durable. Looks great by my pond and waterfall to hide the electrical items.

company ripped me off

Terrible company. The item color didn't match my other rock, and was slightly too small. They want $21.95 to return the item. Nowhere in the description did they say anything about charging a restock fee. Also, it should only cost 6.99 for a shipping label. What a rip off
