By David L. Welch on October 28, 2011
i purchased this 42" vizio tv a couple of weeks ago and so far i am very happy. it has great color i love the internet apps, the high def looks great and even the 3d is stunning. after much research, i found the amazon price very reasonable compared to other vendors, especially considering the fact that i did not have to pay any sales tax and shipping and handling were free. setup was basically easy (i am not real technically inclined) and we had the tv up and running within 20 or so minutes.

i have a few minor complaints but still feel this tv warrants five stars. they are:

1. the sound is not the richest, but most flat screens will have sound which is inferior to a home theater system. thus, i purchased a sony home theatre for my visio and am very happy. cost of the home theater from amazon; $257.

2. the tv takes a little while to come on. i don't know if that is particular to this brand/model since this is the first flat screen i have owned.

3. if you have little children, the tv base that comes with it is not real stable and the tv could possibly be tipped easily. of course if you are hanging it on a wall, this is not an issue. be sure to have your tv on a solid level stand so it will not tend to tip.

other than that i am very pleased with the quality and price of my new tv. now i just hope i don't become a couch potato and gain 50 pounds with my new little toy.

oh yes, one idea i've tried which i really like. i've been storing tons of digital photos on a couple of computers for years. they were really not organized much and i seldom viewed them. since the vizio will play photos or music from its usb ports, i purchased a 16 mb thumb drive and put literally thousands of photos on it, arranged in various folders.

I spent months looking for a TV and finally found this one. After comparing different models i decided on this one for the price. The LED LCD screen at 42" is big enough for all your needs, home theater, casual watching, video games. its excellent, the TV is light and thin due to it being a flat screen and all :P. easy to use menu and set up. the only downside is you cannot turn off the WiFi on it. which tbh isnt really a down side. ive owned it for 2 months now and love it, so my suggestion if you are looking for a TV this is the one

This is my first HDTV after looking and researching for months. There is not much bad I can say about it. Picture is excellent, price is great, and apps are a great addition to the already amazing package. Vizio has upped their game recently and this shows it. I highly recommend it.

This is the best TV I have ever owned. The picture quality as by far the clearest and sharpest around. I work for Verizon Fios and install TV service. I see about 20 different tvs a day 5 days a week, and of all the sets ive seen nothing can come close to matching this quality. The internet app service gives me everything I need at my fingertips. The full qwerty keyboard on the reverse side of the provided remote is a big plus. Setup was a breeze and I'm all set ready to watch anything if its the big game or the news.

Our huge and heavy "old-school" TV finally gave out and we had to enter the 21st century and HDTV. Did a lot of research and this looked like the best fit for us in terms of features, size and price. The picture is crisp and clear, and the colors and brilliant and vibrant. Setup was a snap. We were able to get rid of a switch box that we needed with our old analog set, and with the internet apps -- we no longer need our Roku (although we'd very much like to see Vizio extend its apps to some other services). The only disappointment was our old legacy VCR (as we've still got a few films which aren't available on DVD or streaming anywhere) which because the set has the 3 component video and not the one video RCA slot, just can't be hooked up directly. Overall, very pleased with our decision. Our living room gets a lot of light during the day, and the picture is just as great then as it is with the lights out. The low energy consumption was another plus for us, plus with the fact that we now have two fewer devices plugged in, this will additionally lower our power use. This set has brought new life to our viewing. We don't have a Blu-ray yet so all of these comments are based on viewing that isn't even at its highest resolution. People who've bought other sets have seen ours and have been impressed with the quality and said they'd look into a Vizio themselves in the future. All-in-all a terrific purchase that we have been enjoying tremendously.

After searching the market for a decent TV for a couple of months, I'm happy that finally decided to go with Vizio. Well The picture quality is perfect and competitive with Sony or Samsung. The sound quality is not perfect(like most of other lcd tvs I've seen) but good enough.
I connected the tv to wifi and streamed videos from Hulu, Netflix, Vimeo and Amazon, the quality was absolutely astounding. No lag at all.
The remote control is small and quite easy to work with at the same time.
There is only one down side to the Vizio Apps though. I haven't been able to stream Youtube videos yet.
