Aspire Nautilus 2 is a great product. The flavor and steam volume are very good. But please consider its improvement: 1. The lid do not closed on resistance but on the ground as it often blocks itself. 2. Sealing gaskets to be more efficient as leakage may occur. 3. Lower airflow side to be wider and with a flat portion to ensure fastening when removing the lid. It's very difficult to do this being circular and as I said sometimes the lid remains stuck on the resistance. Thank you. Yours sincerely, Nicholas Toth.
