Well, I know some are unsure about docks and cradles and nintendo do make them as bare bones as possible. But they do serve a purpose and i've used mine since I bought it.
Just to reiterate, this smaller dock is for the regular size 'new3ds' they also sell 2nd hand new3dsxl docks but at £12 there having jk.
No charger incuded obviously.
Regardless, with the postage being £2.50 for up to 10 items you might as well have a trawl about to make the deal really worthwile. I noticed some cheap Nintendo branded 2ds cases and some pretty reasonably priced cover plates as well fwiw.
