My biggest regret is never listen to advise given by friends who have bad experiences buying from Lazada. Although the value for the powerbanks I paid is not a big sum but I felt cheated by them as they delivered sub-standard item. Worst still both units of the same brand and model cannot be use at all. Already emailed and spoken to them for the past one-month but still no solution to solve my problem. They are trying their luck to make me giving up claiming from them which I will never. Also never, believe those products review. We can see only good reviews. Bad reviews missing.
