Do Not go through e-cigarette lobby.com! I ordered a black ipv4 from them over a month ago now and it has been delayed repeatedly, they have the silver, black are harder to get anywhere, said p4you is delaying them. When I ordered it from their site it said they were in stock for petes sake and now I'm getting real close to trying to cancel my order. I'm dying to try the temp control, have nickel coils 2 feet away from me... there are a couple places that seem to have the black in stock, vape royalty I think is one, ppl are getting black ones... silver seems to be readily available.
Also make sure you get a batt charger and do not use the 9vlt charge port onboard and definitely don't try to charge thru usb port, take batts out to charge. Some ppl are recommending pulling out the onboard charger chip board due to malfunctions leading to meltdown.
