DDave mods experience

Hey folks have any of you got the Arizer Extreme Q vaporizer? I love mine and recently bought some upgrade parts for it from DDave Mods. Their catalog is confusing at best making it hard to know what it contained in his “packages”. He doesn’t like selling individual parts so one has to buy stuff you don’t need to get what you want. BUT WORSE IS THE PARTS DON’T WORK. They don’t fit my machine and come with parts I have no idea are for. I was willing to pay for one of his packages in order to get what I wanted, only to find that part wasn’t even included in the package I bought. THEN THE CAPPER IS THEY WILL NOT EXCHANGE OR CREDIT ANYTHING!! THEY DON’T GIVE A SHIT ABOUT THEIR CUSTOMERS AND BEHAVE LIKE THE WORLD SHOULD KNEEL AT THIER FEET. DO NOT BUY ANYTHING FROM DDAVE MODS!! YOU’LL REGRET IT!
