DADA

Wasn't sure about the plastic at first but it clips onto the cage bars fine and my hamster figured it out within a day. The no-color-choice thing is a gamble, though I ended up with a blue one that matches his wheel.

The plastic is sturdier than I expected for the price, and it wipes clean in seconds. My dwarf hamster figured out where the food was within a day, no spills on the bedding since.

My hamster started using this feeder immediately, and the plastic is sturdy enough for daily nibbling. The only small downside is you can't pick the color — I got a bright pink one that doesn't match my cage setup, but it still works fine.
