Mini DisplayPort to HDMI Adapter (female) Cable for Apple Mac

I have a 15" Macbook Pro and an Acer computer monitor with an HDMI input. I decided that I should get an HDMI adapter because in the future I could use it with a TV. SO I looked through Amazon and I found this cheap adapter, and I figured that if it didn't work I wouldn't be wasting to much money on it. But I've been using it for a couple of months now and it works beautifully with all the monitors and TVs I've connected it to. It just needs a standard HDMI cable to hook up.
