I bought the same size (in white) when I moved in with Katie. Everyone now is on different sized rodents, and will be for the most part.
Don't like the white, but it's in a basement storage room, so I can hardly complain. Works great and is the perfect size.
At least when Solana (9g baby Corn snake) is full grown, she will eat the same size mice as Figment (adult corn snake).
Shayna (BP) will forever be on medium rats and Behira (2 year old BCI female) will be done with medium rats sooner than later and on to larges and XL.
They are pretty energy efficient these days and it's way better keeping rodents in there than the main freezer in the house!
I have a whole home generator, but if you don't, and lose power, get the rodents out quickly! When moving from my old house to Katie's house, my soon to be father-in-law unplugged the (old) freezer to move it to get to something and didn't plug it back in!
We realized it a week later! Needless to say, the freezer, along with it's contents, got thrown out immediately upon realizing the mistake. I will never forget that smell!
