I bought this swing five years ago for my first born daughter. Although she did not like being in the swing for long, it is a great product. When she did stay in the swing, the soothing ocean sounds calmed her. It lasted through my second daughter. She really loved it and always wanted to swing. We gave it away to another expectant parent that said she loved it as well. We gave it away because we didnt plan to have another child. Well, that changed and now we are going to buy another FP swing. If you read others reviews, they seem to complain a lot. You can hear the motor very slightly. I dont think the three babies that were in my swing had a problem with it though and neither did I. Yes, it does take D cell batteries and yes, they do go out fast, but its a swing!! the batteries last a few days with full power. If you wish to use batteries, spend the extra money and get the rechargeable ones. THIS PRODUCT HAS A AC ADAPTER FEATURE! I would highly suggest buying the AC adapter and saving the money. Overall, FP swings are well made and do the job you bought them for. They calm and soothe your baby! They definitely helped my wife raise my daughter by herself when I was deployed to Iraq. I only buy FP products for all my kids.
