I have the same "crappy" bluetooth range from my Diamondboxx L2. Same deal.....10-15 feet away, and if anybody walks between phone and speaker it cuts out. I also have 3 other bluetooth speakers (Aiwa Exos9, JBL Boombox, and Soundboks) and they all offer far greater range. My L2 is still under warranty (less than 2 years) and I shipped it back for repair/update. Strange that "under warranty", I had to pay shipping which was $75/FedEx. At this price point....I would not consider DiamondBoxx until bluetooth issues are resolved. For those wanting a kickass speaker....check out the new SoundBoks. It plays louder than my L2 and has more mid bass kick (with new app/firmware). I still would give the advantage to the DiamondBoxx for overall fidelity and smoothness....but after a few beers....I prefer punch and volume
