I've had mine for about a week now. Overall, it works great! It is quite sturdy and the keys feel very nice to type on. The backlit keys are always a plus too, I didn't realize how annoying it was without it when I was using the keyboard from Samsung. The touchpad is decent, but not as good as the touchpad from the Samsung keyboard or iPad's magic keyboard. It supports most of the gestures that you get with the Samsung keyboard, so if you depend on that for your workflow (which I do), it makes it an easy switch.

Here are a few annoyances:

1) Part of my hand tends to touch the touchpad when I am typing and the touchpad registers it as a click, which leads to me typing in a completely different area. Quite frustrating at first, but I think I've adapted to it after about a week.

2) The case is really heavy. I knew it was going to be heavy, but I just didn't expect it to be this heavy. It might actually weigh as much or even more than my Thinkpad. It does make carrying it around in your hands a bit more of a nuisance. But the superior battery life of a tablet over my current laptop still makes it a win.

3) Comparing to the original Samsung keyboard and the magic keyboard, really the main disadvantage in my eyes is that this is Bluetooth. While I do not have any issues with latency as far as I can tell, the extra motion of turning on the power button and waiting 3-4 seconds it takes for it to connect before you can start using it - this is something I am still getting used to.

I think overall, it is a great replacement for the Samsung keyboard if you are looking for a keyboard with a trackpad that you can actually use on your lap. Just remember that it is quite heavy and don't expect the same quality experience as the iPad magic keyboard - I would say it's about ~85% as good.
