This swing is really easy to put together and works very well. I like the following features a lot - the flying insect net, the remote, the side to side rocking motion, the built in lullabies, the bluetooth feature and the three different positions from upright to laying down. The three different positions for my baby to lay, recline, or sit up are great because babies can be fussy! It took me a little bit to realize you have to push the switch under the front of the swing all the way up to maximize the motion of the swing, but once I figured that out it swings side to side very well. The swing states for infants up to 20 lbs. My daughter is almost 6 months and still small, so no problems there. I probably should have gotten it sooner!! The music is also a great feature, especially since you can connect to your phone and play different sounds! Overall it is a very nice sturdy swing with all the key featuresThis swing plugs into an outlet for normal operation, however, I would like to see a battery option as well so it could be moved more freely or taken outdoors. Since it is powered by a USB cord, that is plugged into a wall adapter on one end and the swing on the other, I plan to try to buy a small $8.50 USB battery pack and see if that will power it as well. I might even try a lithium ion battery pack that charges phones. If the specs match the swing specs that could be a winner! Stay tuned!
