I think this is a cool idea; however, after paying $299 you only get 5 calm and 5 energy strips that are guaranteed for one time use. After that they cost $19.99 for another 5. This would be a very expensive "habit".

Obviously worth it if it enables you to work - e.g., lots of people pay for lattes etc.
