I have owned this for a while and it works fine.
One caution however, if you are considering this for use with windows media centre then it's important to know that you will not be able to receive the hd channels e,g BBC hd. This is not technotrend's fault but Microsoft as WMC doesn't support dvbs2 properly (yet). It doesn't send the right tuning information for dvbs2. However at least one other manufacturer of similar devices has gone to the effort to provide a workaround and technotrend do not hence only 3 stars from me.
This caution does not apply if you use other media centre software.
