We purchased this product as a Christmas gift for our 5-year old son. The set is adorable and is easy to set up and operate. Thankfully, we opted to purchase the 2 years service plan, knowing that model trains can often have mechanical issues. Despite very gentle and occasional use, the Thomas train stopped working approximately 7 months after we purchased it. Walmart's service plan department was EXCELLENT! They asked us to return only the defective train and they refunded our entire purchase price, including tax. It is important to note, however: once you use the service plan, it is considered "fulfilled" and cannot be used again. As a result, we will be purchasing a new plan when we reorder the set. Not a bad deal at all, though - it only costs us an additional $14 or $15 when we reorder. Even if we have to go through this process every year, it will be worth it to ensure our son's train is always in working order.
