this review title is: charger design sloppiness norelco shaver arcitec and the content is: as of october the instructions specifically say that you must unplug the norelco arcitec shaver from the charger once it is fully charged if you do not you will hurt the battery i guess you are supposed to baby sit it every few hoursthis is an inexcusable design error and the principal reason i am returning this product for a full refundif norelco had said on the box you have to watch the battery icon till it stops blinking and then you have to unplug the shaver i would not have wasted my time buying it would you.there are other information for this review, one is this reviewer did not purchase it and the other is 29 people think this review is helpful.
