Bests & Worsts Reviews from Amazon

I recently purchased this refurbished soundbar as a replacement for a soundbar that broke that I had for 6 years. I got it home, set it up, and here is what I found: I didn't think that soundbars could sound this good. It makes my old soundbar sound like a complete piece of garbage. Even when listening to classical music at full volume there was no distortion. It really is that good. The app to control it is very cool. Some really sleek functions are on there. Unfortunately that is where my praise ends. After watching a movie on it it started making a horrible siren sound. I disconnected the power cord (As that was the only way I could make it stop) and reconnected it. It did it again about every 30 minutes to an hour. I contacted Vizio customer support who were very quick to respond. First they had me cycle the power by unplugging it and holding down the power button for 30 seconds. After I did that it worked again for a couple of hours and then made the horrible sound again. Then they had me do a hard reset. That seemed to make it worse as it would make the sound every 30 minutes or so after that. Sometimes the sound just comes out of the front speaker and sometimes it is the rear speakers (See video). If you leave it on long enough it will come out of both! It sounds like the ghost of William Wallace is haunting my soundbar! The next email they sent me said that they wanted to replace the unit. They gave me the (Advanced replacement) option to put a hold for the MSRP of the unit on my credit card while they sent me the new one until they received the defective one. The other option was to send it back to them and wait for them to get it before they would send me a replacement. I chose the advanced replacement option. Later that day they sent me an email saying they didn't have any units to replace mine and would simply have to refund my money. I said that would be fine as long as it didn't take to long as I would be completely without a soundbar until I could order another one. This was their reply: "Before getting it set up, we will need to go over some guidelines. See below: 1. The return authorization is only valid for 30 days from the date of approval. After 30 days the refund offer will expire and no refund will be given. 2. We will provide a label and packaging material if needed. Once the return location receives the unit it takes approximately 1-2 business days to check the unit in. 3. After the warehouse checks the unit in it takes approximately 7-10 business days to start and finish the refund process and cut the check. 4. After the 7-10 business days, there will be an additional mailing time of 3-5 business days to receive the check through the US mail. 5. Total time frame is 4-6 weeks including transit time for the unit to be returned to us. . To get started with this, please reply to this email with your full name as displayed on your photo ID and your physical address." 4 to 6 weeks I have to wait to get my money back for this thing? Honestly the soundbar sounded so good that I went ahead and ordered another one and I guess I will wait the month and a half until I get my money back for the first one. This thing has huge potential and this specific problem seems to be very rare with these units. Hopefully you have better luck than I did. Cheers, Ryan
