Customer Reviews

Poor quality product. After installing the first attempt, the battery lasted only 1 hour. Just after 2 months, it failed completely. I rather buy a China made battery than this USED battery which the company disguised as NEW. Got cheated of my RM180. My mistake I didn't contact them earlier to arrange for a refund due to my busy schedule. This review is to ensure others don't fall prey. If you know your ethics please call me.
