I have be very impressed with all of Vizio 's product . I purchase the vht510 almost a month ago and have not have any issue . I have be wait for the lead issue to pop up but have be fortunate enough for that to not happen yet . the sound quality have be great . it be definitely highly recommend to use a optical cable versus the rca jack for optimum sound quality . setup be quick and easy . the wireless feature have be great for ease of setup due to not have to run wire across the room .
