Warranty support
I had purchased one of the folding keyboards and was loving using it for 10 months at work. Suddenly the letter A stopped typing properly. I've emailed the tech support and although it was a long time between answers, within 4 emails they have provided me a new unit under warranty. All I had to do was email them a video of the issue. Found the overall experience simple and good. Even though slow, the outcome was better than expected. The product itself is good and reliable. I have no idea how many thousands of times I have pressed that letter A in these 10 months of use.
