Amazing Keyboard!

I purchased the K3 Max about 3 weeks ago and I love it! I've been using it for everything work related and it's been holding up great. I'm very happy with the quality of the product and highly recommend it if you are into low profile keyboards. Getting the Max version to have the 2.4 wireless connection is totally worth it. I actually just purchased a second K3 Max so that I have one in my work office and my home office.
