I purchased this from Amazon US and have used it for 4 years. It still functions perfectly well as a keyboard, but a part of the stand is broken, so the 8° angle is unusable. Besides that, there are scratches here and there, but there were no particular problems with volume adjustment or typing. I used it a bit roughly, so I'm listing it as a junk item. I used it in an environment without a cat or smoking. Shipping includes the keyboard and receiver only. Since this is a layman's inspection, I will clean it simply before shipping. Please understand and accept it as-is, no returns.
