Picked a couple up from NP. Perfect for me since I am at school and the library for ~8 hours a day. Seals good, seems durable(only had it for a week, can't comment on long term). The compartments for pills and powders are extremely convenient since I don't go home a lot during the day. I don't have to waste snack bags anymore. All of my powders have mixed well with only the mixing grate on there.
Great product especially considering the price
