Great Corporate Customisable Gift for Developers $100- $200

Hi ozb,

I'm searching for a great gift that would work well with developers (or generally technical/IT) people somewhere that can be customised/personalised.

  • Price $80-$200/item
  • Items: 50-100

I'm looking for something that will not end up in the rubbish bin after 10m of being used.

Thoughts so far:
* Smart Watches - e.g. Ticwatch: A bit expensive and can't figure out a way to customise it
* Phone Power bank - meh, over used in promotions because it's cheap
* Drones - fun initial use but most probably will end up being used after first day
