Hi, you've read this hundreds of times, but you REALLY need to add a brightness control feature. Yes, i've searched on google and found the reddit thread. I go with them too. Sorry but it's actually a joke the way it works now. The light sensor doesn't work properly and sometimes it turns off in a way that putting the hand on the keyboard doesn't turn it on, so i have to press a key everytime to turn it on. I wouldn't be writing all of these issues and complains if a simple always on option and stuff were available. "Oh but the battery won't last all that was designed for". Well, it's a give and take. That's why it comes with a USB cable and PCs have USB ports. And while I got my hands off the keyboard to read what i have written the lights shut off and i barely could see anything. So, yeah. This keyboard IS a great product. But fix your keyboard or fix the software. Or both, maybe. Thanks and sorry for any language mistakes!
