I have been a customer for years. I have fought the battle of Plexaderm's many issues with product dispensers. I could tell a few stories, but no need. The latest issue is with both the single round and the single with the funny look and "screw" off top. Both are terrible and because I don't cover my face with the product, I lose at least half because it hardens. I even put in a zip lock back to remove the air.. still lose product. Absolutely the worst! Seems with the price and the advertisements dollars you must spend, you would make a dispenser that works and give me the full product I pay for. I plan on finding another company that satisfies. Calling "customer service" provides no help at all, but does provide an attitude.
