Overall Impression: This cup has a great reputation and following. It's a very nice cup for those looking for the firmest cup on the market for what ever reason. This has been nicknamed, "The Rock" for that reason. It opens without any help and stays open! It's very popular for people that are very physically active. If you have a sensitive bladder, this is probably not the cup for you. The large size of this cup is a little longer than most "average" large size cups on the market. Because of that, the large would most likely be more comfortable for someone with a medium to high cervix.
