This is the most amazing keyboard I have ever owned. I purchased this identical keyboard 5 years ago. I only bought another one because I have a public desk at work, and an office as well. The main one is very worn in, but has been amazing for 5 years. I’ve only had to change the batieres 1 time in the entire life of my first one. I just repurchased this a month ago, and I love it just as much. Great for the money, and having 2 wireless pieces with 1 dongle is great!

Definitely a ton of value with this purchase!
