There is no suction cups. The product was NOT as advertised. It was loud, buzzy, and could not be used. Awful.

Rated 2 out of 5 by Marie123 Only works half the time.
After two months of use, both of my whisper filters don't work like they should. I clean them regularly and change out the filter as directed but there is little to no water flow out of them right after I clean them or after about a week.

Rated 1 out of 5 by SadTetra I cannot attach whisper 3i to my tank.....
I think that Tetra Whisper filters are amazing products… However the new innovative clip attachment method falls short of the functionality of the simple suction cups. Because of this, The filter I bought is completely and utterly useless, because I cannot attach it to my tank properly. Instead of flowing properly and filtering in my tank it sits there and bubbles because of the angle at which it sits. Thanks Tetra...
