Query: For Celebrity Chefs Only: Keep Band-Aids Nearby

I thought the KitchenArt Adjust-A-Cup looked really useful all the times I saw Alton Brown use it on his "Good Eats" show, however, real life demonstrates this product has a number of fatal flaws and seems only useful for televised pre-prepped cooking demonstrations. Complaints:-Choppy/sudden movement mentioned in other reviews is easily remedied by oiling the rubber wiper but this creates a host of other problems (stains, contamination, gumminess),-The sharp bottom edge of outer cylinder frequently injures a finger when plunging -made especially bad by the aforementioned choppy motion (and my inherent clumsiness).-When washing, the inner cylinder permanently fills with water -a serious health concern as harbored bacteria could contaminate newly measured ingredients.-The rubber wiper leaks, is fragile, and tears easily.This list of negatives far outweigh any positives I can think of and mine went right in the trash after only a few uses.
