magicJack: PC to Phone Jack Immediately

Don't buy this product. If you must buy it buy it from Magicjack so you get the 30 day guarantee. I bought it here on Amazon and once installed the audio would cut in and out. I worked with Magicjack to re-install their software but the problem continued to reoccur. The Amazon seller would not let me return and would not refund my purchase. I contacted Magicjack and they said they only issue refunds to those who buy direct from them. On another note, the software slows down your computer. I currently have cable phone service through Comcast and it works fine so I know it wasn't my internet connection. Buyer beware!Get more detail about magicJack: PC to Phone Jack.
