To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I picked this up on special to use as ambient lighting for my tv. I've seen some people complaining that it doesn't come with the Hue Hub, but it also says that in the literal first sentence of the product description, so you know, learn to read.
You definitely don't need to use the Hue HDMI Hub to connect to a TV for active ambient lighting though, I found an $8 app called HueDynamic that does the same thing using your phones camera. Use a cheap mobile stand, point at the tv, and it works perfectly. Colour syncs perfectly with whatever is on the screen, regardless of where it streams from too, so less messing around with cabling and pass through, and saves hundreds of $.
Works well with voice control as well, I've got mine synced with Google, so I can control the lighting without touching a thing.
Great value, and really makes watching movies a better experience all around.
