I bought the medium resistance grey band, it has been great so far, I am still learning how to use it. The Database, however, is really lame. You have to download the file, then you get a list of exercises with vague titles, each with a link that sends you to a short youtube video demo of the exercise. No description, no explanation, just a little video. That is inconvenient and you have to keep replaying the video to understand the exercise. If you are trying to learn a routine, you have to keep opening and closing different youtube links, this makes it really difficult to learn the exercises and keep track of where you are. PJF should really consider creating a physical booklet with pictures and written descriptions of each exercise. TRX does this and it is very helpful. The resistance band itself is cool
