"Used quite a few blutooth speakers over the years and this one is a WINNER. The new "handsfree" feature while paired with my iPhone is incredible. Would highly recommend."
"I received the speaker about 2 1/2 weeks ago and have used it with an Android phone (droid) and tablet (nexus). The Bluetooth only works with line of sight so if anything is between the phone/tablet and the speaker, the connection significantly degrades or you will lose it completely. You definitely can't have the phone/tablet in one room and the speaker in another room. Range is barely 15 feet with line of sight. You also can not control the volume from the phone or tablet. The volume can only be controlled from the speaker which is a huge pain. I have other bluetooth speakers and can control the volume from the phone/tablet. This speaker obviously has a very poor implementation of bluetooth. I brought these issues up to Shark customer support within a few days of receiving the speaker but after one email exchange, they never got back to me with what they would do. After two weeks of use and using it at times at about 3/4 volume, the speaker is now showing signs of distortion. I only give it two stars because it does have reasonable volume and good battery performance. I would not buy it again and I would not recommend this for purchase even at this price point.
(Update 12/17/13) Customer service got back to me and sent me one of their other speaker models, ASIN# B00D4CQAS2. I believe it has an older version of blue tooth and it works great. The Android phone can control the volume and the BT range is over 30 feet. It is smaller that the original speaker and the sound quality is even better. As a result I have raised my rating from 2 stars to 4 stars on the basis that Sharkk Customer support worked to understand the problems I had with the original speaker and replaced it with a different one at no cost. Excellent customer support."
