I ordered this Kahuna watch because it has a large face, and at the same time looks feminine. When it arrived it was not working. I returned it to Amazon for a replacement. The replacement was not working either. I phoned the manufacturer, who said that both the batteries must have been dead, so the watches were probably old stock. Because this had happened twice, they offered to replace the battery free of charge. I had to pay postage to get the watch to them, but they did not charge for return postage, nor for the battery. The watch is now working perfectly with the new battery, and I am very pleased with it. I am very grateful to Kahuna for replacing the battery free of charge. However I am most disappointed in Amazon that they twice sent me watches with dead batteries. I give Kahuna full marks, but NOT Amazon, as I feel they should have checked that their stock was working before sending it out.
