First impression when I opened the box.. Wow, thats tiny! 
It weighs less than half an AA Eneloop.
The front Low CRI LED outputs seem to match specs of 5 lm, 50 lm, and 150 lm.
The High CRI white sidelights (on my meter) measure 2.5 lm and 15 lm, per side.
Here are some Opple measurements:
Comes with a quick release necklace and has a tailmagnet.
Includes a USB-A to USB-C charging cable, making it a complete package.
Things I wish were different:
I would prefer the front LED to be High CRI
I would like the Red mode to be constant ON
I would rather only one side was illuminated, to prevent the beam reaching my eyes.
There are blinkies in the sidelights, in white, red, and red plus blue.
Next time Im at a Rave, or want to impersonate LEO, I will be tempted to wear the necklace.. 
The UI is Very easy to use, it clics on and off at the last used mode.
Overall It is a cute little light with several potentially useful modes.
This could be a good gift for someone’s keychain.
