Hi Cheryl, welcome to the forum and thank you for your post. You are right in that there are not many comments about the comfort of the Noogleberry cups. I must admit also that from a customer service point of view, i get very few emails about this. The cup brims are rounded and smooth and we use hard plastic. It will be interesting to see what comments we get back about this. Once you have had chance to read the replies, i would be happy to sell just one cup so that you can try it before you buy a complete system. If then you want to go ahead i can take off the price of the cup. Its just a thought to try and save you money.
best wishes
Lucy
