Sigelei Great Wall (GW) Review

Updated on: 2018-03-12

First Impression Out Of The Box

All I can say when I pulled this thing out of the box is ‘wow, what a big mod.’ This is really a handful. Then again, it’s exactly what you would expect from a dual 21700 mod. It does have a nice shape to it but make no mistake about it, this is a big mod.

I was a little surprised at the packaging. I received two of these mods for review and one of them came with a set of Sigelei 21700 batteries installed and the other had no batteries. I’m not sure if Sigelei is selling this as a kit, one with batteries, and one without. I have not been able to find any information on it and all of the listings that I have seen list it without any batteries. So, they might have provided some batteries for the reviewer samples because 21700 batteries are kind of tough to get your hands on right now.

What’s In The Box

  • One GW Box Mod
  • Two 18650 Adaptors
  • One Micro USB Cable
  • User Manual and Warranty Card
  • One mod came with batteries installed, the other did not

Sigelei GW Review

From Top To Bottom

Starting off at the top of the mod, we have a center mounted 510 connection. This 510 connection will hold a 28mm atomizer without any overhang. You can get a 30mm atomizer on it but there will be some slight overhang on the back side of the mod. It is the type of overhang that will only bother the most anal retentive users. It’s a shame that Sigelei didn’t beef this mod up a little bit more on the top plate, so it is able to hold 30mm atomizers without any overhang.

The GW does have a stainless steel plate going around the threading of the 510 connection. The threading is nice and smooth and so far, all of my atomizers have sat flush on it. The 510 pin is gold plated and it has a nice stiff spring to it, with what I would call a medium throw. So far, I have enjoyed running my Aromamizer Plus and Vandy Vape Triple on it.

On the backside of the mod, there is some Chinese writing with what looks like a tree. On both sides of the mod, in the tubing with a battery is held, you will see some artwork on the outside of that tubing. They look like Chinese scenes from The Great Wall of China. There is also some Chinese writing on them. I have no idea what the writing says but it is on there. To be honest, I could definitely do without Chinese writing on a mod that I am using in America.

The battery door for the GW is located on the bottom side of the mod. The compartment is made for 21700 batteries. It also accepts 20700 batteries. With one of the mods to fit, I have had no issues with any rattling or battery door rattle. On the other mod that they sent, I did have some significant battery and battery door rattle, no matter which batteries I used. So it seems like the QC on this mod may be a little bit of an issue. Because one mod had significant battery and battery door rattle while the other had none. They also include an adapter so you can run 18650 batteries in this mod but I have no idea why you would want to do that. This mod is extremely big, especially if you’re only going to run 18650 batteries in it. I would do that only if I was in a pinch and did not have access to 21700 batteries yet.

The door on the GW is the push down and out sort of door. It is hinged and on the inside, it has gold plated button style battery contacts. The battery contacts are clearly labeled plus and minus. Inside the battery tubes, we have two gold-plated spring loaded battery contacts. There are no battery orientation markings inside the tubes. There is some indirect venting on the battery door but I definitely would have liked to have seen more.

On the front side of the mod, we have a large oval shaped fire button with some Sigelei branding on it. It looks to be made out of plastic but it does have a very nice quick and feel to it. It is also a nice size button that is perfect for thumb firing.

Right below the fire button, we have a screen that is laid out in vertical form. It is a .96-inch TFT color display. I like the font that they used and the way that they laid it out. It has plenty of information on it and the font is large enough to be easily readable. On the screen, you’ll be able to see your resistance, voltage, locked or unlocked, watts, temperature, puff counter and individual voltage of each battery. There is also a battery meter at the bottom of the screen.

Below the screen, we have two diamond-shaped plus and minus buttons. They are very small for a mod of this size and I think Sigelei would have been better off going with much bigger up and down buttons. They have a nice clicky feel to him but I still wish they were bigger. Right below the diamond-shaped up and down buttons is where the USB port is located. This port is for charging and updating. However, given Sigelei’s track records with updates, I wouldn’t count too much on an update.

The Look, Feel, and General Aesthetics Of The Mod

This mod reminds me an awful lot of the Vfeng. It’s like a bigger, more smoothed out version of that mod. It has the same overall shape but it doesn’t have the corners and edges of the Vfeng. It actually has a very comfortable form factor and even though it’s big, it is comfortable to hold. I do like the way it feels in the hand but I could have definitely done without all that Chinese writing all over my mod. To me, that amounts to some pretty ugly branding.

Sigelei GW Review

When you do run 21700 batteries in this mod, it is pretty heavy. This is not what I would call an all day carry but at the same time, it’s not so big that I would classify it as a coffee table mod. It’s the type of mod you would take in the car with you on a long trip because of the extended battery life and the fact that you probably wouldn’t have to swap out batteries too frequently. Because of its size and weight, it would probably do really well in a nice-sized cup holder.
