We bought this product for our son at christmas. The first one didn't work and we had a very disappointed two yr old on our hands. Unable to return the item to where we purchased it originally we contacted the company direct. They agreed to replace the product, second one received that too was faulty. We contacted the company again and another replacement was sent. Third time lucky. The clock is working well, our two yr old adores it and loves putting Thomas to sleep at night. Overall, my advice is contact the company direct if you are having problems, details on the box. Worth the money when you get one that works!
