The flash was great when it worked. A month after purchase (on the 3rd use) the springs broke off in this flash. I contacted the seller to return it as the return period was closed the day before. The seller sends spare parts for repair, I agreed to this. Find out the part was shipped from China, I had to wait 3 weeks for the part!. Finally got a part to attach the springs, now the whole flash won't turn on. Even the battery was charged. 02/27/2020: I contacted the Antoso seller for a refund. The seller refunded the money in full after I sent the flash back. Good customer service. Bad flash.
