The K830 is a good solution for HTPC environment and looks fine yet I find the battery life is not so good specially when using the illumination in dark situations. They could have easily added a better capacity battery but for some reason they didn't. Also If when the battery dies you need to throw away the whole keyboard. I have had 2 of them during the years but the battery life is disappointing. The K400+ is a cheaper solution with exchangeable batteries to go with if one don't care about the illumination or the looks.

Useless overpriced metal box. Played with one for a day and MAN what a piece of junk. - Connecting it to an advance WiFi home network is a pain in the lower back. - Unbelievably laggy UI. - The manufacturer claimed that it will work with any touch screen: NOT true didn't work with my Acer touch screen. -Sounded extremely V shaped no matter the output source, Way below average. In theory It should be a great product but in reality its not, Avoid.

Brilliant VR work out game!

In one word the Swans F2.2a sounds: Sublime.

Utter Bullshit wow factor. Got it on Friday and sent it back next Monday, Very cool concept with the WoW factor. But: Out of the box 2 dead pixels plus 4 stuck pixels and low pixel density is very low across the panel. Cheap plastic construction, The panel itself gets very hot + from specific viewing angles such as if you stand above it or come from a side there is very noticeable panel flickering. The worst of all is the back-light bleeding, One of the worst cases of back-light bleeding I've ever seen on any panel. The built-in speakers never worked. When you turn off your PC and it goes to standby mode, overnight it switches itself off and the next day it won't turn on with your PC until you physically press the annoying fiddly power button that is placed at a very un-ergonomic position.

Does the Job it supposed to do but with compromises: - Too pricey. - Absolutely no smart "app" functions what so ever. - Replacement filter are expensive and un-washable. - The ionizer resales Ozone gases. - Gets very loud If the end user wishes to reach effective results otherwise its pointless. - Bulky "big" & Construction aka "plastics" feels cheap. + Gathers a lot of dust and particles. + Good coverage range. + Effective sensors. + Kills odors and annoying smells.

+ Acceptable price point. + Effective and looks nice. + App and setting-up is a breeze. + App functions are handy. + Works with Google home. - Filter life span is short "Even if air quality is excellent" ca 140 days on mixed " low and medium level". - Filter replacement and Availability online in Sweden is problematic for an acceptable price.

Good little sounding speaker with SD card reader is always a plus. But: The battery starts dying in a less than a year and I haven't used it much. In less than a year you will have to charge it often and it won't hold the charge for long. Very annoying especially its a sealed construction and the user can replace the battery. So its either needs to be connected to power most of the time or just throw it away after a year. (dispose of it properly)

While wearing the M2's and walking the headband creates air turbulence generating a sound that resonates within the cans, Not ideal for walking. ANC is good but cannot be deactivated yet you wont feel the artificial annoying pressure many of other more expensive ANC systems offer. NFC is good to have. The multi-controller is fiddly and not ergonomically thought through, Will need some time time to get used to. Good and timeless build quality in general. The app is useless. Its basically a player with EQ. Aside of Tidal there is no other streaming service support up to this moment. Sound wise in music is about acceptable but nothing to rave about. Call quality is very good according the the receiving-end of the conversation both on cellular and within apps. For under 1800kr new they just about ok. 5 out of 10.

The best solution for a quiet HTPC build.
