A first device that has never managed to "repeat" the signal from my router was replaced by the seller. The scope of the second device fluctuates randomly. Sometimes (but rarely) the signal is correct sometimes it is low or non-existent. I made contact with the seller who refused to exchange or repair. Moreover, the seller disreputable that treats its top customers, has simply stopped answering my emails. It remains for me to find a more efficient product and especially a vendor-conscious customer complaints. Amazon former client and good customer I think, additional premium, I can not recommend this provider to dereference that has no place on the Amazon site. This is the first time I complain a direct or indirect benefit from Amazon to whom I nevertheless retains my confidence.
