I have two devices of this kind and I am delighted! They allow me to record my TV shows on my computer to watch later. It's very simple to use and the software is pretty intuitive. If you want a very good reception picture is better to connect directly to the Elgato TV outlet. If not, you can use an indoor TV antenna (mine works fine with Elgato). However, the reception by the two antennas is not ideal. Attention also to the version of your computer OS: too old, and Elgato software will not function. So check before purchase. Personally the two elgato I installed work perfectly, and I'm thrilled !!! I .eyetv exports the files into readable file on my iphone and ipad, I copy everything on my key "Photo Fast I-flash" and I can see all the EyeTV recording when I want on my ipad and iphone. The combination of the two products is over the top ... I highly recommend.
