[This review was collected as part of a promotion.] This speaker is a beast in its class of party speakers. It is power packed with 240W RMS, which gives amazing sound when you are partying in your backyard or in an equally large place. Few of the best features on top of the sound are - The lights that gets displayed on the speaker, which are in sync to the music being played. - With the draggable option, It can be transported easily like your cabin baggage. - It can also be paired with other bluetooth speakers or other speakers for even louder music. - Being water resistant, you need not worry of partying with JBL 310 in a drizzle. - Amazing playback time on battery. My tag for JBL products are J - Just B - Buy it and L - you'll Love it
