I bought this charger on Apr 2024 and i had 4 batteries attached to it , it worked good until two weeks ago, so i contact the customer service, and they ask for video of the malfunction , so i send them the video, its been two weeks and nothing been happening, they offered me $30 for what, i don't understand , i need a replacement or complete refunds. On their website they are saying " hassle free return " . So far its been nothing but the headache. I guess thats why is cheaply priced .
