The Roku Streaming Stick 4K, sold under model number 3820EU, is a £39.99 dongle that plugs into an HDMI port and streams in 4K, Dolby Vision and HDR10+. It finished second in this guide, with 4.4 out of 5 from 1,682 ratings on its Amazon listing, and a histogram where 70 of the 100 ratings shown are five-star against 7 one-star.

What earns it a place in this article is not the hardware but the paperwork. On the same page, the specification table gives this stick an Item Weight of 22 g and a Memory Storage Capacity of 32 GB, alongside 1 GB of RAM and Item Dimensions of 14.2 x 5.8 x 15.6 cm — a footprint whose volume does not sit comfortably with a 22 g device. The listing also returns a Country of Origin of Japan. Nothing here has been measured by us: every figure, price and rating on this page is copied from the Roku 3820EU's own Amazon listing, and the contradictions are the listing's, not ours.
