To praise is the extraordinarily high willingness of the seller quickly to deliver a replacement. Unfortunately, the disappointment was great, and this obviously had the same defect. I laste this is not the seller to, who is bound to the information of his supplier and must believe that. Incidentally functioned both power supplies properly to a FRITZ! Box 7170, which is satisfied with 1.0 A, while the FRITZ! Box 7270 is at least 1.5 A requests.
Again kudos for easy unwinding by the seller.
