I recently purchased the Harman Airplay Wireless Speaker System from Groupon for $169. The unit sounds like crap, no bass, no volume, Airplay disconnects all the time. This has been the worst Groupon experience. Groupon will not accept a return. They are requiring me to go to Harman. Harman will not take it back either. DO NOT BUY A GROUPON GOODS! There is no support! GROUPON SUCKS!
