this be a wonderful keyboard with correct `` 6 '' spacing and excellent comfort level . it have be very durable for the 3 month that I have own it . in fact , everything be perfect about this keyboard except that the letter have all wear off . yes , I be a medical transcriptionist and type 40 + hour a week on this . I know this be a lot of use , but I keep remember the IBM Selectrics that I learn on in high school that be 30 year old but still have all the letter intact . even the paint on the symbol key be wear off , which could be a problem as I do not have these memorize . I be really irritated about the cheapo letter paint . I hope it be not toxic as I have absorb it all in my fingertip .
