Reviewer comments on business characteristics

Sigelei presents the GW, it is a mod declined in different colors but it is above all a massive and overpowered machine with a power capacity of 257W and a weight of 300g mini for two 18650 batteries. Of course with this possibility out of the ordinary, the batteries will have to adapt to the machine that can also accommodate 20700 format batteries and up to 21700, ie if the autonomy can be felt. At the same time, this GW from Sigelei is made to delight the coilers who execute resistances out of standard 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 of the 1.0 color TFT type. It does not seem huge compared to the template of the product, but the information is in a format sufficient to distinctly distinguish each part. 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 TFT screen of 1.0 "is rather correct with a writing format and a very functional organization. The color screen and the beautiful brightness bring a very appreciable visual comfort. The knobs are undersized but perform their function. In contrast, the switch is a massive knob, oval zinc alloy, with the name of the manufacturer, SIGELEI, engraved. It is perfect and does not move a hair with a nice 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.

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 format 18650, 20700 or 21700
- 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 316 stainless steel and 317 stainless steel for temperature mode with the possibility to change the resistive with the TCR
- The resistance range is from 0.05Ω to 3Ω
- Lock function of the settings
- Power setting function with preheating time
- 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 accepted wires are Nickel, Titanium or Stainless 316 and 317
- Possibility of recharging the box via the micro-USB cable
- Update chipset via micro-USB cable

The securities are also present with:

- Detection of the presence of the atomizer and the resistive value
- Protection against short circuits
- Warning about the charge level of the battery
- Protection against overvoltage
- Overheating protection
- Balance detection between the voltages of the two batteries
- Reverse polarity protection on at least one of the accumulators

This box offers all the functions sufficient for a product of this type for a power of 257W.

Vapelier's note in terms of usability: 4 / 5 4 5 out of stars

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, we must recognize that this GW has charm ... except my color test that I do not do. Fortunately, Sigelei offers many different colors to satisfy its customers.

Except for its weight, the format and the ergonomics are quite classic. 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 outsized capabilities and all security 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.
