The first impressions are confusing. It's evident that a lot of thought went into developing this device, and on the one hand it's a very intriguing answer. However, several keys' locations and sizes are open to serious doubt. It will take a long time to get used to, and not only to letters but to function keys, and the number of misses in the beginning will be really frustrating if you have been blindly typing on a regular keyboard for a long time. Despite the keyboard's intended role in relieving stress, he started to feel pain in his hands. The size makes it tough to move around the desk easily. Work will crumble into flour if the countertop isn't wide enough to accommodate the forearms. The smooth action and responsiveness of the keys are undeniably positive aspects. I didn't like using Excel spreadsheets, but this would be a nice option for people whose jobs only include text.
