Reviewer comments on business characteristics
Sigelei presents the GW to us, it is a mod available in different colors but it is above all a massive and overpowering machine with a power capacity of 257W and a weight of 300g mini for two 18650 batteries. Of course with this possibility except Normally, the batteries will have to adapt to the machine which can also accommodate batteries in the 20700 format and up to 21700, which is to say if the autonomy can be affected. At the same time, this Sigelei GW is made to delight coilers who perform extraordinary resistances with very low values.
You will understand, this box is not made for a daily vape but to send heavy.
It offers, in addition to the conventional power mode, temperature control with common resistive such as Nickel, stainless steel (SS316), Titanium or even the TCR by adjusting the temperature coefficient of the resistive used. The starting resistance is 0.05Ω.
The screen is 1.0 ″ color TFT type. It doesn't look huge compared to the size of the product, but the information is in a format sufficient to distinguish each part distinctly. In addition, the different colors and brightness of this screen help to read well.
Be careful, however, to properly adapt the batteries you use, because the GW has a maximum discharge current of 38A, which does not allow 18650 batteries to use this box to its full capacity. In case of use beyond the 150W, prefer more powerful batteries in 20700 or 21700.

Reviewer's comments on physical characteristics and perceived quality
The GW is rather ergonomic with an oval shape and convex on the front. Its top-cap is equipped with a stainless steel turntable with a double pin spring-mounted pin which is in addition, adjustable by a gold-plated screw. The platinum is smooth but remains a bit small with its diameter 20mm facing this mastodon that can accept 30mm atomizers.
This box is rather impressive and is not lighter but we quickly get used to the weight because the format remains common. The location of the batteries is easily accessible, without a screwdriver since it has a sliding hinged cover and articulates effectively without detaching. Inside, there are two rubber adapters that allow the use of 18650 batteries. In addition, these two parts are provided with a wide metal contact which is crimped on it to avoid loss of adhesion in the continuity of the current.
The 1.0 ″ TFT screen is pretty decent with a very functional writing format and organization. The color screen and the attractive brightness provide very appreciable visual comfort. The adjustment knobs are undersized but perform their function. On the other hand, the switch is a massive, oval zinc alloy button with the manufacturer's name, SIGELEI, engraved. It is perfect and does not move by a hair with a nice support surface when the mod is in the hand.
Under the adjustment buttons, there is the opening provided for inserting a micro-USB cable for recharging or updating the chipset.
For my test, the coating of the GW is zinc alloy with a matt light brown coating which, to my great regret, is "plastoc". Some will surely appreciate, for my part, I find that this fairly basic color is reminiscent of children's toys. For this product, it is a color that contrasts much with the zinc alloy mirror look that we see on each side of the box and are beautifully engraved with Chinese drawings and inscriptions.
The finishes and bolts are perfect. A coherent set that adds to the overall look masculine, it must be admitted, the box.

Vapelier's note regarding functional characteristics: 4.8 / 5 
Reviewer's comments on functional features
For the functional characteristics, they are quite simple and common face to the different models of boxs equipped with more powerful chipsets but the most important is there with:
- 2 batteries in parallel in 18650, 20700 or 21700 format
- An output power of 1 to 257W with a maximum discharge current of 38A so be careful to take the same two batteries with the required characteristics.
- Two working modes in power or temperature
- The wires that can be used are Nickel, Titanium or stainless steel 316 and stainless steel 317 for the temperature mode with the possibility of changing resistive with the TCR
- The resistance range is 0.05Ω to 3Ω
- Adjustment lock function
- Power adjustment function with the duration of preheating
- Choice of display in ° C or ° F with a range of 100 to 315 ° C or 200 to 600 ° F
- Puff counter
- In temperature control, the wires accepted are Nickel, Titanium or Stainless Steel 316 and 317
- Possibility of recharging the box via the micro-USB cable

Reviewer's comments on the use of the product
GW Sigelei is very easy to use, a chipset that wants to be efficient and simple. The organization of the menu is really very intuitive, it was a pleasure to navigate.
For ignition, the operation is done in 5 clicks. The access to the resistive choices in 3 clicks and, to scroll the functions, it is necessary to use the buttons of adjustment and confirm the choice with the switch.
To lock the adjustment buttons, simply press the [-] and the switch at the same time.
On the other hand, I did not find any possibility to lock the box and thus the risk of accidental switching of the switch is possible but only during 8 seconds because the box goes off automatically beyond.
So much for the main lines related to the use.
Side vape, there is nothing to say, this GW is reactive and fair, its vape offers a fairly linear rendering. During my tests, I did not go beyond 190W but I can assure you that it sends and remains stable in the rendering vape. The correctness of the requested powers seems exact according to the resistance achieved.
For ergonomics, we stay in a fairly common format, only the weight is higher than most boxes in the market but we adapt.

The mood ticket of the reviewer
Even if I'm not a man, I have to admit that this GW has charm… apart from my test color, which I don't get used to. Fortunately, Sigelei offers many different colors to satisfy its customers.
Except for its weight, the format and ergonomics are fairly standard. The zinc alloy on the edges of the mod gives the product a superb elegant look but beyond the aesthetic aspect, it is also a chipset with extraordinary capacities and all safety is assured.
With 21700 batteries, the GW has an incredible autonomy, it is especially appreciated by associating with exotic montages which, very often, are big consumers in energy. Of course, it is also possible to vaper cushy 30W with this mod that works well but the weight is disproportionate to vape in this way.
The assembly is well done, it is a product of good quality but I still have some reservations on the durability of the hinge on the battery access door. I regret the diameter of the plate which, 25mm, would have been more suitable.
Sigelei can be proud with this product which keeps a good quality / price ratio.
