Great mod Review by Martin
I had originally purchased the predator, after fighting it to remain in temp mode, random misfires it finally gave up and ejected it's 510 connector from itself. Return to here was great, no issues and they gave me a store credit. I've had several Sigelei devices in the past and never had an issue so even tho I had read about previous issues the company had, all I could do is go from my own experiences. Glad I did, very solid mod, I actually like the 510 in the center for various different rda's. Nice heft to the mod while not being ridiculously heavy, screen is informative and easy to read, fires when and how it's supposed to. Really, only complaint I have is the battery door at times comes partially off but a quick squeeze and all's well again. I honestly think it's how I hold the mod, pinky finger on the bottom and I must inadvertantly press the release.

Not Impressed Review by Teresa
Let me start off by saying that this particular review is not meant to diss Sigelei on the whole. I have owned many Sigelei products and have always found them to be of the best quality, they're usually tough as nails. I likely got the one dud out of the bunch with the Fuchai Duo-3.
From the get-go it seemed to lack power. Slow ramp-up with any tank/coil I put on it. Two days after I got it, I used it for one entire day before parking it on an end table in my living room. Four days later I tried to use it again and it wouldn't power on. And that was the end of that...
It's in the return process now (which is very smooth and easy here BTW), and I hope to have it replaced within the week.

Solid Device Review by jtm215
Super fast shipping. Arrived in perfect condition. Great looking device with big screen and easy to navigate menu. Solid Build with no button rattle and battery door is rock solid on the one I received. 510 pin spring loaded, centered and all my tanks fit and function properly. The screen has a protective layer, so if you think it's scratched just peel off the layer and pristine screen underneath. I peeled from USB connection and used tweezers to remove. No defects found on paint finish. Five star device with good power, battery life, and big colorful screen. My new favorite vape Mod !

Great mod for the money Review by Brian
It has been working great for me I love that the 510 is in the center makes all the tanks look great and you can fit a very large tank on this mod 30's fit fine. I do wish that they gave you the third battery door with the mod it kinda sucks cause I know they are gonna have it but I'm gonna have to buy it when it should have come with it. The menu is very simple to use and the info available on the screen is very useful. Handles the higher wattage build with no problem.

Love this mod. Perfect size, love the fact that the tank goes in middle and you go all the way up to 30mm diameter with no problems.
