Hi BLF!

The Wuben G2 is packed in a plastic box. The front gives some basic information about the flashlight specs, while the back doesn’t have much relevant information.
Inside, protected by white foam, we find:
Wuben G2 flashlight
USB to USB-C cable
Pocket clip
User Manual
The Wuben G2 is mostly done in aluminium (body), while the top and bottom are hard plastic. The USB-C cover is rubber.
In the top we have the W switch button, an indication LED and the USB-C port.
The sides have some grooves for fitting the pocket clip.
The bottom of the flashlight can be covered by a keychain adapter, removable and with a split ring attached to a rotating pin, or it can be naked and flat, allowing to use the magnetic tail or just to sit it on a flat surface.
The bottom also has 2 screws that hold the flashlight in one piece. This is the way we can access the internals of the flashlight (NOT ADVISED).
In the front of the flashlight we see a flat metal bezel/frame around a*textured TIR lens*, that allows the Osram P9 LED to put out around 500 lumens in a wide beam, with very few artifacts.
The Osram is not High CRI but this combination produces a smooth flody beam with a roughly defined “hotspot” (if we can call it that).
In the back of the flashlight, we have the Serial Number and…compliance symbols.
The pocket clip is installed by the back of the flashlight, with the tip towards the bottom, so that it fits the side grooves of the flashlight. It is removable, but not reversible. To install it, just apply some pressure till it “clicks”.
The retention it gives is good but it is not the strongest. The clip is made form plastic, becoming more malleable than a metal one. It serves its purposes, namely on thicker fabric. It is versatile enough to allow using the Wuben G2 in a shirt, pocket, cap, or backpack.
As for the keychain adapter, it can be removed by slightly twisting it counterclockwise and installed by putting it in place and twisting it clockwise. It has some small flaps that fit the keychain slot, so they need to be aligned to make a good rotation. When installed it doesn’t come out easily.
The indication LED serves two main functions, which is to indicate:
Charging status
- RED = charging
- BLUE = charged
Battery Level
- Constant Blue
- Blinking Blue
- Constant Red
- Blinking Red
The USB-C port is protected by a rubber cover, that can be pulled up to place the charging cable.
The included USB to USB-C charging cable is short, but it can be handy to take on a trip of to use it in pocket organizer, if you need it.
According to specs charging takes around 1.5 hours. I haven’t checked this myself, but for previous experiences, I’d say that it is accurate, given the battery capacity/size.
The flashlight can be used in 3 levels only while charging !
The magnetic tailcap is quite convenient and strong and it hold pretty well in different types of surfaces.
This allows using this flashlight as a small worklight, if needed, as it can be attached to different surfaces.
It is also strong enough to keep the split ring of the keychain adapted lifted up 
As seen above this is a compact, small, thin and lightweight flashlight, that easily fits in a pocket, coin pocket, backpack and eventually in some wallets, without the pocket clip, of course. It becomes slightly larger, thicker, longer and slightly heavier when the pocket clip and the keychain adapter are installed. But just a few millimeters or grams 
Above we’ve seen excerpts from the User Manual, but in the photos below you can check the whole information. This part is written in English while in the back there is information in other languages, without too much detail.
USER INTERFACE, OUTPUT and RUNTIME
The user interface in the Wuben G2 is quite simple. It has last memory mode for the regular levels, which is one of the few things I don’t enjoy so much in this flashlight.
From OFF:
- press & hold the switch for 0.5s = turns the flashlight ON in the last used mode
- double click = Turbo
From ON:
- press & hold the switch = advances through the levels in the sequence Moonlight > Low > Medium > High > Moonlight …
- double click = Turbo
- single click = turns the flashlight OFF (from any mode/level)
That’s it, no blinkies!!!
As for the output and runtime, I have no means to confirm (accurately or not) the values presented by the brand.
However I can say that:
- Moonlight level seems higher than 1 lumen (when compared with other lights)
- Turbo drops within 56seconds and then gets stable (I did a 5 minutes test only)
- The 46m range seems accurate in terms of max range for this flashlight (tested it in the beamshots)
NOTE: In the 5 minute test I did, the flashlight just got warm, which I think is a good thing as it shows that there is good heat dissipation and that it doesn’t get very hot, overall, due to the drop down. In such a small light, it wouldn’t be advisable to have high temperatures.
FLASHLIGHT COMPARISON
Time for some size comparison and not only!
First of all, a reference to other Wuben flashlights using the same type of textured TIR optics, namely the Wuben H3 (https://budgetlightforum.com/t/-/66040) and Wuben D1 (https://budgetlightforum.com/t/-/66110). The beams are more or less similar, ones being stronger than the others, though.
Then, the Wuben family, with some members missing here! 
And now the comparison with other flashlights, namely in the same category of keychain flashlights!
Lumintop Frog > Trustfire Mini X >Wuben G2 > Nitecore Tip > RovyVon A8
BEAMSHOTS
And now, time for some beamshots to show what the Wuben G2 does in the dark!
First of all, there is no visible PWM.
As for the beam pattern, as you probably guess and as advanced above, this is a floody and wide beam with a roughly defined hotspot, almost inexistent.
There are very few artifacts in the beam, just some slight tint shifts that are due to the type of LED. There are some “rings” visible on lower levels, but that do not interfere with the functionality of the flashlight.
And here is the comparison between the Wuben G2 and the other keychain lights presented above.
Nitecore Tip > Trustfire Mini X >Wuben G2 > RovyVon A8 > Lumintop Frog
And now against the Wuben D1 (Luxeon V2 4000K).
Some distance beamshots

OVERALL APPRECIATION
Honestly, there more things that I like in this Wuben G2 flashlight than things I would change.
It starts in:
- quality of construction, without machining or assembling flaws
- good UI (although I would make some changes), particularly without blinkies and with shortcut to turbo
- good beam, homogeneous, without many artifacts, and despite the Cool White and Low CRI emitter
- magnetic tailcap to attach it to different surfaces and eventually use it as worklight
- size, weight and compactness
- versatility of use, be it through the keychain adapter or the pocket clip
- USB-Rechargeable, since I don’t need to bring extra cables
——/////——
However, I am picky, so I would do some changes namely:
- use a High CRI LED, since it is a keychain light, eventually used for small distances, which can benefit from a better colour rendition
- introduce a shortcut to the lowest level, although keeping the last memory mode
- lower the lowest level (moonlight)
