Well TV said I can either buy a new core for $35 or send it in to get rebuilt for $15... kind of disappointing considering the only thing I did to ruin my Revolution was use dark colored oil.
So I offer these words of warning to all revolution owners, use only bright yellow, very clear when melted, wax.
Using dark black or brown oil or wax will slowly destroy your Revolution, it will clog the ceramic to the point the it is irreparable. Cleaning is deceptive, it will work afterwards but you will notice it start to clog quicker and quicker after each cleaning.
I've tried harsh solvents and extreme heat, believe me when I tell you, my Revolution was well and truly killed... by normal, everyday oil that you see in dispensaries all the time. I had it for less than a month. Didn't even use it every day...
My personal rule and my heartfelt advice to anyone wishing to keep their Revolution in working condition is to only feed it PureGold or the clearest of clear $50 waxes, I haven't actually seen an oil that is light colored enough not to damage the Revolution yet so I would advise avoiding all bho's.
Save the cheap oil and wax for disposable Omicron carts that you don't mind clogging...
