I own this product for about a year. The functionality could be used better and better with each firmware. Special highlight are the Gigabit interfaces, really bring also this throughput. Perfect if you operate several sub-networks in the home network. Unfortunately, the first device was no longer can be used to vorausgegagenen crashes last. I suspect a hardware defect. This can happen at any time, but that's what the guarantee. In my case, the dealer has absolutely no problem assumed the thing and I got sent to about three weeks a new device. My networks run recover as usual. For the smooth processing by the dealer Varia-Store two stars separately. Can recommend as a reliable dealer.
