Dear Customer, Thanks for your comments - and while we do appreciate customer's feedback on their experience of our product, in your case it appears that you did not actually purchase or use the product - and are just expressing your opinion. In the case of plungeMAX though it touches the rim and though the rim may not be clean as you said, however there is opportunity to clean the rim using a paper napkin before using PlungeMAX - however no traditional plunger that goes inside the bowl can come even close to PlungeMAX in terms of being sanitary. It appears that for you "touching the rim" is same as "going inside the bowl full of gunk" - it is purely your personal perspective and not something that many people will agree with. Your comment about functionality is not accurate, the PlungeMAX does operate well when used properly as directed - which is no different than following directions to seal and clear clog with any regular plunger. If you still have questions, please reach out to us at sales@pfwaterworks.com and we will be happy share a lot of details including functional videos of the product and answer any specific questions you may have.
