I ordered this one for $18:

But that was after I'd finally found one 1/2 that size at CVS Pharmacy (with no auto shutoff) for the same price. Walmart and Walgreens both only had the auto-shut off timer. I'm going to keep both of them, never hurts to have a spare and it'd cost more in gas to return it than it'd be worth.
I'd have liked to use an aquarium, I've got so many here. But a screened lid would've cost more than the $6 each for these 3 tubs. And in an aquarium you can watch them, and they're really pretty cool. I set 2 slices of orange in there and they headed for it immediately. Didn't bother then a bit that some giant old woman was peering down at them from above lol
You pimp you, oranges are just like viagra to them!
