I thought the idea would be great, hide my airlines under the gravel so when I vaccum the gravel, the lines don't get pulled up. So I bought it!
I feel foolish though... I can't assemble it!
There are 2 pieces:
(1) A suction cup with a round peg [and a round hole in the peg], I assume to attach the holder.
(2) The holder which holds the hose perfectly... only the peg [that should fit into the round peg on the suction]... IS LARGER AND SQUARE!
It sounded like a good idea, but fitting a square peg into a smaller round hole has done a number on my fingers. Let me know if I missed a step.
Next time around, put gravel over the tube and a rock to hold it in place.
The Bottom Line: Pass, spend the $2 on some feeders for your Oscar or JD. He'll thank you for it.
PS I checked the website, in case I missed a step. It was as helpful as the bar code on teh back of the packaging.
