The product was excellent and worked perfectly but the product was missing two key parts (charger and hot shoe) and I was unable to return it because the seller didn't consider it considered merchant. The seller offered to buy two pieces, but I already bought it. I was only able to test the product because I bought it brand new and had all the parts. The missing pieces had to be uncovered. I ended up paying more for a flashlight with extra parts than just buying a new one.
