My wrist hurt if I type on a regular keyboard or laptop too long. The ergo shape of this keyboard helps greatly. Performance The feel of the keys is good and solid. Like the lower profile keys. Durability No issues yet and I have had it for about a year. Design Like the extra buttons (volume and mute are the most used). good ergo feel and looks good. Comfort I have another ergo keyboard at work and I like this one better.
