Sigelei GW 257W Review Bottom Line

The Sigelei GW 257W mod utilizes dual 21700 batteries to produce an awesome battery life. It also has the ability to use traditional 18650 batteries so not all is lost for those traditional vapers. With all the features you could wish for and manufactured by a reliable name Sigelei, this mod is one of the best you can get.

The Sigelei GW 257W Mod Kit

In-depth Sigelei Great Wall (GW) 257 Kit Review

Sigelei have had a great year for releasing box mods and they have ended the year with another great release, the Great Wall (GW) is their attempt to create a mod with the longest battery life and all the functionality every type of vaper need. In this Sigelei GW 257W review we’ll take a look at the kit and see if it competes with the best vape mods and see if it lives up to its reputation.

 

Design

This mod is ultimately designed to use the traditional 18650 battery along with the 20700 and the 21700. This means it comes with collars to add to the smaller batteries to ensure a snug fit. The designers, therefore, had quite a task producing a mod that can fit these larger batteries in, yet still achieving a small looking design.

Different Designs of the Sigelei GW 257W Mod KitWe think they achieved their goals, not only does the design work really well with all the batteries, but it also looks real full-color   Yes, it’s a little bigger than the traditional, 2 x battery mod, but not enough to really notice.

Made from Zinc alloy with some cool Chinese letters down the side along with a full-color TFT screen this mod screams class! For the money, you do get a lot of stuff and a great mod, but make sure you check out our vape devices where this and mods like it often pop up.

 

Performance

So how does this mod perform? We tried it with the 21700 batteries and can say that the battery life is awesome. Vaping all day, pretty much all the time this mod lasts! Granted it probably wouldn’t if you were firing it at full capacity of 257 Watts!

The responsiveness of the firing is also really good, making it a pleasure to be used and vape with.  With the 18650 batteries, the device works just as well, but the only drawback is the awkwardness of having to fit the tubes on the smaller batteries. I’m sure you would get used to this though!

Is this mod for someone looking to quit smoking with vaping, probably not as it has too many features and the F Tank is really designed for those direct lung inhales.  Also as it’s a little larger than the traditional dual battery mod, it’s probably not going to suit the person carrying it in your pocket all day. That said if you’ve used a vape mod before, you’ll have no problem using this mod and probably fall in love with it.
