What to buy a 13year old boy?

[Ohdear2016]

What are you buying your teenager this Christmas. We usually stick to smaller presents but this year I planned to get him something bigger, but what? any suggestions? Thinking of a phone, hoverboard, remote control something?

My ds is getting a ps4 (combined birthday and Christmas present), a lava lamp,clothes and lots of star wars bits and bobs.
I think drones are quite popular too.

Got DS a drone for his birthday and he likes it. They also do car versions - still fun but you won't ruin granny's perm on Christmas day.

I've got DS a kindle fire and the accosiated gubbins. I got one last month and he said he'd like one.

Also got him Lego, a Nerf crossbow and a Sega Megadrive handheld thingy which I bought instead of the New as I really couldn't get hold of one.

Few other DVDs, CDs and games. T-shirts with gaming stuff on. Spare earphones, etc.
