Agree with the two previous review comments.
Please be aware that their is another fundatmental design issue and hidden cost not explained in the product description!!!
You must have at least TWO HDMI cables to use this device! (an input and an output). i.e. To connect my PS3 I need a HDMI cable to connect to the Switcher and another to connect the switcher to the TV.
No HDMI cables are included in the package so if you don't have a spare already then you need to buy one.
The low score is for Joytech's poor design (they should include a cable or incorporate one in the design) and Play.com's poor marketing (not expalining this).
