Got an Eson today bought privately, i buy a new mask every six months ish to keep things fresh and try something new and wanted another nasal mask as the Sleepweaver Elan though comfortable isn't working for me so i have been using my swift FX mostly. First night impressions are good, easy to seal and lightweight, some strap marks this morning but probably from side sleeping and being a little tight. Will make a full review after a few more nights.
