Rank #2 in Best 4K Streaming Stick 2026: 10 Ranked, and the Spec Tables That Don't Add Up
Roku Streaming Stick 4K (3820EU), Black
Price and rating as shown on Amazon when we collected them. Both change.
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.
How those 1,682 ratings break down
An average hides its own shape. This is the spread behind the 4.4 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Bought to replace an aging Fire Stick, which struggled to work with EE WiFi (after BT had helpfully forced us to change from Plusnet). The Roku has no trouble with EE WiFi6, is quicker then the Firestick, and has a nice simple interface. Shame the pre-programmed buttons for Netflix, Disney, Apple TV and Prime can't be changed. Of those, we only have Prime, but rarely use it.”
Verified purchase“Easy to install and turns my Sony Bravia TV, which although smart it is quite a poor smart system, into a faster smart TV, although you do have to sign in to all the channels again.The stick plugs straight into the HDMI and powers from the USB so is completely hidden and this version also has volume control on the remote as well.”
