First off I didnt think I would use a plastic grinder, my daily is a cosmic but I like the idea of these all in one deals. I have not heard anything about them and just wanted to check with my blades on gc to see if they last and are good for a travel/throwaway grinder storage container. Brothers with Glass has Medtainer for pretty cheap so I will prob scoop one either way and report back if no one has a review.
Some guy at a party I met was using one. It seemed hard to use and always got stuck, though that could be a lack of cleaning.Personally I'd go for something like then mendo mulcher or space case
