The only thing that’s hard to decide is which my 2 year old nephew likes better, Truck Tunes or Twenty Trucks! He simply LOVES both and I could not be happier with the DVDs. He already knows two or three songs by heart, and he has only had the DVDs for a few days. He can now name more construction vehicles than most adults I know thanks to Truck Tunes! I strongly recommend these DVDs! The only complaint I have is, since I want to maintain my favorite uncle status, I now have to find a toy Delimber somewhere! Excellent work! Quality product – and Excellent service! When the post office lost my first order, the company stepped up and overnighted a replacement in time for my nephew’s birthday! Looking forward to the next DVD!
