All modes have been confirmed to be working. The included nozzles are unused. Everything is included: the outer box, instruction manual, and warranty. I'm selling this because I bought it last year and only used it three times before I no longer needed it. I accidentally stepped on the warranty card and it's pretty creased... but it's still usable, and the guarantee card is completely undamaged (a stroke of luck). After purchase, I will re-confirm its operation and clean it before shipping. I hope someone who can't afford a new one from the official online store will buy this! I'm extremely short on money, so please buy it as soon as possible!!!! Thank you very much!!!!
