I too have had a really bad experience with this company. I have read EVERY response Nancy has posted to "defend" herself and her Sound Specialty company. I dealt with her because no one else answers her seemingly one person company. She ripped me off on the price of her product from what was advertised on her website. She then way overrated the abilities of her product and then when we followed every *** direction she and her packaging says to do, the product just simply FAILS MISERABLY to do what she claims it can or will do. I REALLY had to LAUGH at her saying she would've given those people refunds if they only provided a "original proof os sale invoice from her company". WHAT A LIAR!!! WE provided an invoice and she not only REFUSED us a refund for her defective SUBPAR *** product, but then ignored all emails and phone calls to her business. This Nancy person is someone NOT to do business with and STEER CLEAR of doing any transactions with her company. I only WISH I read about all this terrible shyster character and the previous business she has done with other consumers of her products DON'T DO BUSINESS WITH SOUND SPECIALTY
