The product works perfectly, which is limited to the absolute basics. It loads batteries - no more. It does not have a charge status display, no beeps, no bells and whistles. It charges batteries and switches the charging after about 8 hours automatically. Furthermore, one can only batteries in pairs, invite ie 2 or 4 batteries simultaneously. So far this worked perfectly. Batteries were fully charged and there were no failures.
This would give 4 stars for me because of the comfort. For the reasonable price (Due to an offer by the end of 2013. Amazon bought for 11,20.) However you get included 4 AA batteries. Owing to the overwhelming price / performance ratio, the product gets a clear 5 star recommendation.
