I purchased this product for one use only: on the beach so that 3-4 people could enjoy music. While the product is well built, sturdy and seemingly waterproof, the SPEAKERS ARE VERY WEAK. You have to be within 4 feet of the speakers to even hear the music, and even closer if you want to hear it at a reasonable volume. Add in the wonderful beach sounds of wind, waves and idle chatter and this product is forgotten about in 2 minutes.I returned it for a full refund.
