Has anyone noticed or used this o! Light from geonaut

I was in search for a lightweight, portable usb rechargeable headlamp, under 30$.In doing so I stumbled upon these.These were released in 2015 ,but I didn't notice it until now.
This can serve as a headlamp ,torch and bike light by using various accessories.

Has anyone bought or noticed this product,from geonaut before.They are Sold in dacathlon site across the world.I didn't find a thread here about these either.Seems like a good choice for edc jobs.
If anyone have any info or experience with these please share.

Sorry I can't help you with that particular model, but have had a couple of decathlon headlights and a 1xAAA torch and found them all to be trash.

Seems like not many have used or seen this before. well it seems like a cheap option to try anyway.
