Easy to use
My wife said that (the blue one) was easy to use and comfortable, a bit tender in the morning, but got used to it. This helped with snoring a little bit, but not drastic assistance. The clear/white one was again easy to use, but did have a little issue staying in all night. This one she said was noticeable helping her breath at night. Both are easy to clean and she plans to try to continue using them.
