I've been using them for years and can't even imagine using anything else by now!
Well designed and well built, user friendly, and pretty much virus free.
(since most all viruses are written to infect PC's, not Macs)
Never had one crash (not that it doesn't happen) and have been using them for 20 years.
Bought one for each of my daughters and they have never had problems either.
Cost a little more, but sometimes you do get what you pay for.
You might want to consider them if the price fits your budget.
