Power Plus Swing

This swing is nice as far a saving money on batteries. I no longer have to spening money. No more late trips to the store for batteries. This nifty swing can be plugged in to the wall. But i have noticed that the swing does not work like it is suppose to. First off it has 6 speed settings and 3 volume setting. (plays music to). It makes no difference what setting I have the swing on it only swing at one speed. The volume has a mind of it own. Sometimes when I have it set to low it play high. Or if I have it set to high it plays low. I have called fisher price about the swing, cause my baby was still small and the swings suppose to hold up to 25 lbs. I had only had the swing about a month. Well when i did call they asked no question (good customer service) and sent me out a new motor. I was happy til I found out that it was a whole different color lol.My swing does not match anymore. And the problem i had with the first motor I have with the new one. I normally keep the volume off now ( i don't care for the song choice anyways)and I don't let the swing speeds bother me. Even with all that being said i would buy this swing again if i had to.
