I ordered 12 bulbs from LED_Lo seller of Ali Express (Order no. **************). Out of 12 bulbs I received 10 bulbs defective. Inspite of raising dispute with Ali Express nothing happened. They believed their Seller and finalized dispute in his favor with ultimate loss of USD 42.35. Never purchase from this seller and never trust Ali Express for their warrantee. Chinese will ultimate remain Chinese i. E. Cheaters.
