Query: well designed product

Over all, the product is fine. Easy to install, very user friendly, well designed(the instruction booklet can be stored in the unit) and lots of songs, tunes and sounds to choose from. However, I had to return it because it was not loud enough for my 2-story 2500 sqft home and my mother who is hard of hearing. The unit is designed to handle 2 extra speakers, but I did not want to run wires along the ceiling. I did have an issue with the shipping, but Smarthome bent over backwards to help me.
