I be a previous owner of the Vizio vht210w and be some what satisfy with it be performance . the sound quality be not nothing to ramp about but it be a much improvement from just have tv speaker . I recently purchase the vizio vht510 and I have to say I be very impressed . sound quality be amazing for the price I pay . 5.1 ch be clearly a much improvement compare to the 2.1 ch on the vht210w . besides the 5.1 ch the soundbar itself sound much more crisp from the previous model . the subwoofer give a much cleaner deep base compare to the previous model which sound a bit muffle . the remote be alot more responsive . overall , I be very satisfield with this sound system . the only complaint I have be the wire speaker . it would rather have the speaker wireless rather than the subwoofer wireless . BTW , many of the poor review for this system be mainly about durability and functionality issue . since this system be new , the first batch probably have some glitch . I have my system a little over 2 week and still work flawlessly -lrb- knock on wood -rrb- . if you be look for a affordable system , definitely consider this one . I would definitely buy this system again unless a newer model come out .
