This was a necessary item to have. I purchased the set to split with my daughter. A day into our cruise, my sea pass card fell off because of a bad snap. Fortunately, my daughter noticed my pass on the ground and I did not lose that. Here you see that I used a hair tie to "repair" the lanyard to be able to use it. Her lanyard worked well for the whole cruise. This is why the stars are only 3. One was great. The other was faulty. However, both were needed.See full review
