Used to upgrade memory in Mac Pro 2009. No problem. It fits perfectly and works well. I don't think this is one of the famous companies and to be honest I bought them because of the cost. After a few months no complaints. Remember that you want to use a manufacturer's memory. You won't play well if you mix them up.
