You have made no effort to say what type of gear you have supposedly been using, but did manage to say that you had the capability of switching tanks, earlier in the thread; only that they were eBay purchases, on the cheaper side. Since then, ad hominum attacks.It IS a legitimate question. I DO dive without the health and softy nonsense.
Look -- I took the time and answered your "legitimate" question about full face masks, this morning; the least you could do is regale us with your buying prowess -- list what you actually have on hand, brand-specifically (a photo would be nice), since I seriously doubt that you even swim or dive at all.
Convince us that you're not some incel in a basement . . .
