This is a product that I wanted to review for a long time but finally I had the opportunity to review it because I own one. This is the Speakaboo Bamboo speaker and I love this because it makes your smartphone as loud as 90's cassette boombox speaker. You will just put your smart phone inside the whole while it is playing music and it will sound very loud. It saves you money because it doesn't need electricity and it saves you space because it is smaller than most speakers. I can't believe something made of bamboo that doesn't use electricity is louder than some commercial speakers out there.You won't have the hassle of wires and chargers.
