Review on 🖥️ Black USB Wired Ergonomic Keyboard and Mouse Combo - Microsoft Comfort Curve Desktop 3000 for Business (7ZJ-00018) by Christopher Tillman

I don't know what "transparency" means, so I gave it a neutral rating. Ergonomics and thickness are ok. The function is fine. It's okay to type letters, but the arrow keys and numbers are too close to the letter and each other; It would be nice if they were more common. The keyboard needs legs on the back to lift it up. It has non-slip areas on the bottom of the keyboard to keep it from sliding, although I had to put a thin book underneath to tilt the keyboard a bit. The keyboard was packaged in the original box that came in the Revain box but there was no packaging, no padding, no paper, no bubble wrap, nothing to protect so the keyboard box was just slammed shut inside the Revain box. This is completely carefree, carefree and fun and may damage the item as it is electronic. If the keyboard is not working, this is most likely the reason. So obviously, Revain doesn't care about its customers or the items they order.
