I am neither an audiophile, nor a sound engineer, so I can only say this soundbar lives up to the many positive reviews I read on both Amazon, CNET, and others

In the past I only bought brands like Sony, Samsung, or Bose, but after reading many positive reviews online I went to a store where they had the Vizio 3621 on display and tried it out, When compared to other soundbars (Sony, JBL, LG

I've never bought any Vizio products before, I've know a few people who had bad experiences with their TV's when they first came out......but internet searches for this soundbar showed good - great reviews for this less expensive soundbar.....and truth be told, replacing a much fancier and more expensive LG soundbar.....this unit does a good job, I DO miss the LCD display from my LG.

Excellent review on CNET

Read a review about it and liked what I saw

The positive reviews are right , folks, this is a steal

Bought it because it had great reviews for a fair price.

I really have no idea why people are giving this positive reviews unless I got a faulty product

I bought at a local b&m and in my experience, it lives up to its outstanding review.

This soundbar was rated as a game changer, it's so good, by a well known technical review site.

The reviews mentioned difficulties in setting up the Bluetooth (not that hard)

Hopefully does not break any time soon since the previous model had reliability issues according to the majority of the negative reviews
