I became a fan of 4Moms since my first child was born. At the time, I bought their pack and play because it was so easy to set up. I then purchased the first MamaRoo. It has been almost 5 years since then, and they continue to create great products. I am now on my 3rd child, and got this new version of the MamaRoo. It is very simple to assemble. You do not need any tools. Parts just click or zipper into place. It includes bluetooth to control the MamaRoo. If you download the App, it allows you to turn on/off the device, to select the intensity as well as the type of motion. To be honest, I'm not certain when you would want to use the App to control it, since you'd likely be close to the Mamaroo, but it allows you to avoid getting down to do it. I thought I would be able to stream bluetooth music, but that is not the case. It still includes a jack to plug in a music source, and you can use the App to start sourcing music from the jack. The sounds are ok. The speakers are not high-quality speakers, but they do the job for the type of sounds that it includes (white noise types).Overall, I'm very happy with this product. My newborn enjoys it and falls asleep easily once it is set in motion. It is fairly quiet when moving, so you don't have to worry about those sounds waking up the baby.
