Hey guys, it might be out of topic, but asking for a help because I have no clue where to sell them.
We were cleaning out a warehouse of ours, and found that there were spare O3D302 laying around on the shelf, sealed, not unboxed, never used and brand new.

Boss told me to have them as a "bonus" for my hard work for them. So here I'am with 9 of them, and have no clue where to sell because it's just a niche thing and not everyone is searching for such a expensive sensor.
Brand new they cost about 1500 Euros (what i could find) but no way im selling anywhere close to that price.

So, guys, any ideas where should I try to sell them, and what would be the price of a single unit?

Thanks!
