Kudos to the seller Special Trends. Unfortunately, the heart of the first delivery was not working because the batteries already inserted oxidized and decomposed the battery compartment. Replacement was carried out immediately. Unfortunately in the second delivery the batteries ran out, so I had to complain again. For Special Trend no problem! After 3 days, I got sent new batteries. Now the heart is lit beautifully and my girlfriend would be ......... and I am also. Too bad that not all suppliers are working as professional in the complaint processing.
