Product delivered quickly and perfectly functioning. Actually very fast charger. Some minor drawbacks, we can not use it at night in his room :-) It makes the sound of a plane taking off because there was a fan in the charger. The charger does not plug directly into the wall but a transformer that it is connected to the wall (it takes a little space). Especially he struggles to recognize and recharge the batteries of his "colleagues" all my non Duracell batteries are often rejected ...
