Excerpt: Our accounting department ordered two of these keyboards Almost ALL of the letters and numbers rubbed off. Once we contacted Logitech about replacing them, they INSISTED that we return the defective product before they would replace them.. This procedure took almost three months to complete.
Summary: This is quite literally the worst keyboard that I've ever seen. The main problem is that the keys stick and they don't punch easily, making it very difficult to type. I grew up with mechanical keyboards and can type quite fast.
Summary: The BIGGEST problem I have with the keyboard is that the letters and numbers are thin decals on the keys and wear off very fast, less than 6 months. I am on my second keyboard and this one has the letters wearing off as well and I am not a heavy typist.
Excerpt: When working in a diagram program the wheel is erratic and does not work with the program. Sent an email to customer support, received email replies but no solution on how to fix the problem. Most likely will scrap this unit since I can't return it and buy a different keyboard.
Pros: Comfortable Design, Fast Response, Glides Smoothly, Works On Any Surface
Summary: Chinese made krap for sure. In the first year: Both legs broke off, the caps lock icon seldom appears on my screen, the mouse has many quirky habits, the zoom keys don't work. Other than that it's wonderful.
Excerpt: I had this keyboard for about 1 year. Then I started having problems with keys not typing so I thought I had to change the batteries. Then it started happening more and more frequently. So I went and purchased another one. This one started not working a couple of days later.
Excerpt: This is the second one of these I have purchased in the last 1 1/2 years. With the first one, the keyboard died, but I didn't have the needed info to get it replaced under warranty. So, I bought another. Within a week, the new one died, in the same manner. This time I had the needed warranty info!
Pros: Accurate Tracking, Comfortable Design, Fast Response, Glides Smoothly, Great Features
