Too bad that I was able to load either one of the supplied batteries still empty my original LP-E8 battery an EOS 550D so. Because the device seemed to have a defect (within 10 seconds or the charging LED went out). I recanted my order from Amazon and asked for refund. BUNDLE STAR, however, has placed directly with me and sent me a replacement product. 1A-Service!
The fed me sent new charger now completed its tasks perfectly, as I've expected from this product.
Thus, if you have a problem once, so you can see a very good services be aware of what makes every effort very quickly and be accommodating to substitute for the customer.
