Excellent condition and works perfectly. All buttons / functions work as they should. This is not a USB keyboard, as you can see by the plugin. This is model # RT9470 MS P/N. X09-57989. It is in amazing cosmetic condition as well. The only imperfection is a little mark underneath on the right side of the space bar. I took a close picture and put it in the listing photos. This keyboard has two folding feet on the bottom if you desire that angle. They work nicely. Overall, this is a great keyboard. Please feel free to ask any questions. Thanks!
