I am a customer for a long time and Develo have gained experience since the first generation (14mbits). Unfortunately I have the impression that the new series he has not been tested extensively WLAN 500. I bought the single adapter for 109.00. It should provide all the trays, cell phones, PS3, NAS, and Telekom Media Receiver 303 with Internet in the living room. Works fine if no HD channels is received via IPTV. SD channels is combined with I Pad and mobile. At the high advertised bandwidth is likely both the one nor the other variant pose a problem. The WLAN immediately breaks the connection to all other devices. I hope the Develo relatively fast update brings that solves problems. Because the price is only half the work up for things. Of course, it is clear the 500 Mbit dream interpretation, but even an HD TV channels with two wireless devices should not be a problem but for such a reputable manufacturer! Therefore, there are half-hearted work for only three stars, under full function, I would give five stars! Thus, I have one or the other critics here unfortunately give right to the 200-Fi adapter to function at the moment much better also in terms of transfer rate.
