I really like the Omie Box. We had the bentgo but it doesn't have a thermo department. It's good too but smaller than the Omie. Bentgo is too small for my 9yo, for my 4yo is still good size. freshchalk.com/p/omiebox#re...
Really spending the money for the pottery barn one is totally worth it. I got one second hand and it is still amazing! I plan to buy a new one for next year!
