After 2 months the screws on top came loose and the housing for them totally disintegrated and fell out. I really enjoyed it while it worked. It was no longer under warranty when I contacted Sigelei customer support and they refused to replace it. However I would not accept no for an answer. This is a common problem with this mod. I contacted them again and insisted they replace it since it's a design defect. Sigelei agreed to replace it. I haven't received the replacement yet. I hope I don't have same problem again. Glad Sigelei stood behind their product.

Just like other reviews, once I received my mod as I got it out of the box the top on one side was loose and was popped open on one side. It turned on, but definitely want your product to be perfect brand-new. I'm sending for hopefully a replacement mod and hopefully this time it comes fully intact. The lady on the phone told me I could have it fixed by another shop which I felt was very weird because I just paid 94 dollars for this vape and the tank so I shouldn't have to go anywhere and pay for something already payed for new or wait weeks for something to be fixed hopefully I can update with no problems. Delivery was very quick so hopefully this time everything is perfect.

Recently ordered one because mine had burned out.. was excited to see it finally get delivered only to see the top of the mod was loose. Sent the first one back and waited for my replacement. When that one came in, it had the same issue, actually looks like they sent me the same mod back.. I loved the mod, big firing button, nice size, lights are a nice touch.. still trying to get one that isn't defective.

Screen Cracked on mine with minimal pressure. The Faux Leather Grip Backing is a cheap sticker that will eventually start to slide leaving sticky residue all over the place from the sticker itself. Eventually the top of the Mod Screws stripped and Separated. I really liked this mod at first and really wanted to continue to like it but, it couldn't handle basic wear and tear after 4 months of use

The mod is pretty poorly constructed. My screen cracked from minimal thumb pressure, the sticky leathery patch is starting to slide off and makes a mess of my hands and the top of entire top piece where the tank screws on has popped up a couple centimeters. I expected a lot more!

Its a good mod for a lower wattage vape but not so good with the tfv12 it will only push it wean the batteries or fully charged after about 4 or 5 hits you have to recharge but with the big baby it's an all day vape

Advertising at 230 watts output isn't possible with a current dual 18650 battery setup and chipsets without mentioning pulse with modification which very simply explained is like nitro for your vape drawing much more power for a short burst

Fits good in the hand , has big fire button and good screen. Smok's the Alien!

I bought this mod online here, got it in the mail today. I'm even more happy, than I thought I was going to be! It is a wonderful mod....does everything you need, and more. Good on battery life, as well....and I vape hard, or chain vape, as they call it. It is well worth the money, in my personal opinion, Sigelei makes good stuff, until they prove me wrong!

Screen broke completely after only a few weeks without any drops or water damage. Turns out it's a common problem with these. The vape shop I bought it from tried to get the manufacturer to replace it but they wouldn't.
I'll only order mods through direct vapor for now on. Better prices and a WARRANTY.
