Don't forget to press back+play continuously in order to connect via Bluetooth with the TV. Otherwise, it will only work with infrared like all remote controls, and you will have to point it at the TV when using it. The only negative is that its buttons are harder compared to the original one. But you get used to it.
Update after 1 week: it loses connection and you have to remove and reinsert the batteries (at least one) to get it working again. I probably got a defective one. I sent it back to get the more expensive one.

An honest after market, which works perfectly, does not approach the original much because it does not have the same build quality, nor are the buttons as smooth as that one, but compared to two other after market controllers I changed, it is definitely worth it

Bigger than the original - although it's logical to fit the batteries. All the buttons are hard and make a loud click - not like the original. The central circle, if you press it firmly, does not move the menu like the original, which is often a big problem because you have to press up or down repeatedly and especially on the internet and websites it's a big issue. No connection was needed, it works automatically. I keep it because it's not worth the trouble to return it. I can't say it's very cheap but it's not worth even the 15€. It stays as a backup because my original has some issues in case it breaks.

Owner of a Samsung QN95B TV, the remote control broke, ordered this one and it does the job just fine!
