Been using it for 3 years now. It's been great. It has never crashed or anything even once. Absolutely no data has ever been lost by it. I'm satisfied and it's my pleasure to recommend it. I've been travelling with it to work and back, and it has connected to a lot of computers, and has been through a lot rough use and movement, so belive me I know it's tough as nails too. Go for it. It does everything you'd expect from it. Very reliable.
