Forgot to turn it off so it stayed on for a few days in my bag, then I thought it might not have battery anymore but it still had battery. So I think it should last a good amount of time before having to change batteries

I LOVE this keyboard! It's perfect for what I need it for, just simple typing from time to time with my tablet. It's lightweight and super easy to install.

For $10, you can't go wrong. the only reason i'm not giving it 5 stars is because it is very loud while you type. very loud. not just the key clicking, the sound is kind of hard to explain. button feedback is great. the product looks great. it is the perfect size (full size keyboard but doesn't take up any more room than it has to). i'm typing on it right now and it works great. again, 4 stars because you get what you pay for. it is completely functional and exactly as described. but if you put one next to the $70 Apple bluetooth keyboard, the Apple keyboard is unmistakeaby higher quality. i'm very happy with my purchase for the $10 price. having it in front of me i would still buy this again for $10 over buying the apple model for $70 (i have a macbook air, so that's why i keep leaning on the apple comparison). if you want to connect this to an iPad or smartphone it is perfect. throw it in your backpack and you can take notes and type like a normal laptop. but you won't be upset if it gets lost or broken because its only $10. if you're thinking about buying it, just buy it,

I was surprised at how well this unit worked. It exceeded expectation in every way. The BTC Bluetooth Keyboard connected to both my older Galaxy Tab II and the new Galaxy Tab S with no problems. You can use the keyboard to navigate if you like but I just use it to type emails at this time. Brought this keyboard to use on vacation to type emails quicker and easier. Keyboard is not to small that your hands get cramps, but not to big that will not easily fit in your overnight bag. Keys are the same size as my laptop.
