Sent mine back, iwata eclipse hp-CS. fix or service so opted for the service £40 ish got it back still doing the same very dissapointed. I have a cheap nasty £12 airbrush I got first, have had no trouble at all, let me say I am a beginner, have only been airbrushing since December 2019, so I thought it was something I was doing wrong, both brushes treated exactly the same. I have soaked, cleaned, lubed not lubed,, no difference. Just my 3Penny's worth. Sinjon
