    Firstly, by far, this has been one of the best experiences I've had on EBAY. Not only was the seller very communicative, she was also very helpful. The amplifier arrived as described, and excellently packaged! I wish I had known about this seller in the past, I would have bought most of my equipment from them then! It's really refreshing to have a great transaction with an awesome seller! Overall wonderful experience, and exceptional product! I hope to do business with you all again soon!

    Only 1 speaker was delivered. Evidently orders are for only 1 speaker although nowhere in listing does it specifically state such, and at least one of the pictures shows TWO speakers. Not happy with this purchase arrangement. It seems that I will have to pay return shipping on this communication glitch.

    Product is awesome and showed up in great shape despite how rough it was handled by the shipping company. Great price. The box it came in was rough and tape falling off. Was missing half a clamp. Emailed the seller and they sent me new clamps.
