I've been ordering from Clouds of Vapor for the past year or so and never had any issues so this weekend I ordered some DCT and CE2 tanks. I got the order today but one of the DCT tanks were missing so I sent Bruce an email to let him know. Within an hour I had a shipping notification that he had sent out another tank. Fast and courteous customer service coupled with the quality of goods available at COV is what keeps me ordering from them.
