I mentioned in the P-series TV thread -- the 2017 36" soundbar I got from Vizio turned out to be faulty. It has problems with often locking up, sometimes with high-pitched and LOUD squealing sound. The only way to stop the noise and/or get it operating again is the pull the plug.
I'll be sending it back to Vizio once they email me a shipping lable to get a replacement. Hopefully second time is a charm!
Vizio support very good to work with, so that's nice. Also, when it was working, the soundbar's imaging was very good, and sound decent enough for the price.
