Example Input: I would write about this for days. But why bore you? It works really well, there are no issues that I have seen so far. I called Comcast and they added it to my account and it took like an hour to get it working through them, but it was an issue on their end. Since then, it's working excellent!!
Example Output: Positive Review

Example Input: I installed this on a imac 21.5" as I wanted quicker response, start-up ect. This drive delivers an improvement in all areas of functionality. No cons at all. For those whom wish to install this drive go here: https://www.ifixit.com/Device/iMac_Intel ,then select the imac you have! Follow the guide!
Example Output: Positive Review

Example Input: But if you're just now getting one, you're a day late and a dollar short. You won't be mining you're way to the millionaires club anytime soon with this or any other commercial SHA miner anytime soon. Spend your money on a scrypt miner instead.<br /><br />I have to give this 5 stars though because it does what it is supposed to do. It just isn't worth it.
