J had bought this alarm clock as a gift for Father's Day because he met a loud ring, backup battery and screen visible in the dark But a few weeks later, when I try to install the product, I realize that the device comes with an earthen plug 3 flat plugs (plug United Kingdom, as noted by other reviews that I had not seen in the purchase of the device) On the box, it's just mentioned "Works with 230 volt mains adapateur" It is NOT acceptable that product to be sold on this site without adapter 220 Volts with French cards, or at least a mention of this inconsistency CLAIRE and a link to a suitable adapter (even if you had to buy the more)
