A Lifesaver...with some issues

My wife and I bought this swing for our first baby back in October. The baby loved it and it helped restore our sanity many nights when she was on a crying binge! We bought the swing because it is small enough to cart around to grandparents house and folds up for easy storage. The baby loved the swinging motion when it was on medium or high. Unfortunately the swing stopped working after 2 months of regular use. The music still plays, but no swing. We changed the batteries and everything. Another feature we didn't like is that the safety belt/harness has to connect with 3 straps - one through the legs and then two from either side (like a seat belt) so you cannot connect it just like a seatbelt (say when the baby is swaddled). The music that it plays really doesn't do much for baby either. She loves to look at the hanging characters, but got bored with them when they don't move or light up or anything. Boppy said that they would send out a replacement part for the swing so that it can swing again, but you would expect a product like this to last for at least a year, not 2 months. If we had to buy another swing, we would buy something with more features (lights, motion mobile, swing & bounce, etc)
