Bought two LED bulbs. Told us they did not work. We answered with instruction. Got them work. 1 month later left us a neutral saying "Not bright at all. Disappointed, didn't want to pay return shipping for refund.". Did you just notice the brightness of the bulbs after 1 month? We sold more than 1000 pairs and we did not receive any complaint about the brightness. ebay feedback system is not for you to harm seller's reputable especially you have your reason not willing to return for refund.
