Quick shipping...I'll give them that. I found their site looking for a new mod and they had the best price. I ordered the mod and two packs of coils FOR the new mod. I didn't get a confirmation after placing the order and when I tried logging into the account I created I kept getting an error (for 2 days). They responded back on Monday assuring me my account was reset and should work. Logged in and I didn't have any orders. They sent me a tracking link and I got the mod by Wednesday (nice). I opened the box to find the mod and 1 pack of coils for the mod and then another pack of coils that was not what I ordered. Their website is problematic at best and they say "We're here to help" and "We want you to have the greatest experience possible", but once I told them about the wrong item being sent it was "You are responsible for the wrongly sent item until we receive it back. You are responsible for shipping costs. Please allow 5 days for our team to inspect the product before shipping the proper item out". Really? If this was an Apple product that's one thing since you can't just "go somewhere else", but I'll definitely be going elsewhere after this one-time experience. They will pretend they care until you have a problem. I honestly think this is their way of getting money for old stock (who uses Smok X4 coils anymore).
