Cool looking but magnets are the way to go.

I'm not 100% convinced of that. Magnets are nicer, I'll agree, but for example. The suction cups that come with marine grazer, I've used one so far. That's multiple feedings over the last 9 months. I've never cleaned it up or anything, just jammed a new ring on it. I think, and it's just my thoughts, there are some that are a higher grade than others.
Worst case senario, you could always glue a few on if/when they stop working.
