Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

1Samsung2016 6/18/2016

We did not receive an owners manual w/ the tv, which made it difficult to set up. To download the manual on the samsung website I would have to print it out which is over 170 pages long. The tv is hard to adjust my eyes to because I am not used to it.

The only thing lacking

JohnnyK6845 6/9/2016

The only thing this TV lacks is a completely non-reflective screen. I guess I was used to the screen on my old rear-projection TV which totally killed any reflections from the room. Other than that, I couldn't ask for a better product!

satellite - most channels are jerky and and the voice doesn't match the lips. My Samsung 32" 1080 HD has a better picture. The UHD is just not as good when using lower definitions. I will keep it but not overly happy with it. Sorry Samsung i am a long time fan but am disappointed with this one. no amount of fiddling with pic size or resolutions seem to help.

Gift to us

RlaC 5/4/2016

It was time to upgrade our TV which worked but to use different sources you had to change back and forth with different remotes. With my husband having Alz it was time to simplify. The set-up was so fast and easy, it pretty much did it all by itself. The colors are beautiful and sharp. It is sooo much easier to go to other sources of entertainment with one remote and one button. It is bigger than our old one it is easier for us (59 yrs old) to move being only 41 pds vs 125 pds.

I received this TV as a Birthday gift. It has performed very well. One problem is that the sound does not always increase or decrease when pressing the button. It is also sometimes slow to change channels. If I press 13 it will sometimes attempt to change to channel 1

I have had my eye on this TV for awhile now. When it came time to purchase I started to look at other models as well. I looked at smaller size TVs, different makes but I kept coming back to this one. I am glad that I didn't change my mind. A perfect size and a great picture. You can not beat the price for this TV. We don't how we watched our old TV. The picture is so much brighter and vivid. Very happy with our purchase,

Painful to get started

Martian400 4/14/2016

Yes, the TV works, but the on button is hidden by the Samsung speakers that we bought to enhance the sound. Nothing about the built-in sound system is on the box--NOTHING. There is lots of information about picture quality but nothing about the speaker system--which means that the sound is meager (which is why we bought the additional sound system). And, why isn't HULU installed in the add-ons? Hmmm? Now I am on my computer to register the TV so I can access the user manual to figure out how to put HULU on my TV. My five year old Vizio was simpler to use and had HULU already installed. Shell out the extra bucks to get one of the more popular streaming platforms ready to go. I'm off now to try to get HULU to work on my brand new Samsung TV. Wish me luck. I couldn't do it from the clunky remote. Am I regretting this purchase already? Funny you should ask.

The color and picture are fantastic we had a small problem but contacted live chat and so far the problem is gone so kudos for the live chat, can't wait to use all the great features this has. One of the best features is that it has a center stand so many makes have gone to legs on each end and that won't work for our application.

55 inch, 4K UHD JU640D

YourNickNameFieldIsStupid 4/5/2016

The best TV I've ever had. It combines web applications and clear picture, flawlessly. I can be watching Netflix and jump to Facebook really easy and fast, have the alarm set to turn off and on from Monday-Sunday at any time I want to set each day. Lower the intensity so it doesn't bother my eyes. Perfect size too. I can see the news- the outside temperature without having to force my eye-sight. It does upscale even regular digital shows, and the HD 720p-1080p look extra nice. I saw some YouTube 4K videos and it looks beautiful. The colors really stand-out. Also, the screen must have some kind of anti-glare- I can't see the reflection of my windows or room lights on the screen. I just hope it last me long enough to see shows in 4K. Right now, there's almost nothing out there. (As of Apr.5, 2016)

Ease of Setup - All most automatic

CatSam 3/17/2016

I installed the TV yesterday (3 /16/16) without any problems at all. I'm continuing to make minor adjustments such as brightness, color, etc. I know its a matter of personal preference so when you can easily make these refinements its nice to be able to have those features on the TV . The TV setup automatically looked for and quickly found my WI-FI router and range extender, so I don't expect any difficulty in working with the internet. At this point I'm very pleased with the product.

New features include wifi access with plenty of apps and of course a beautiful 55" picture that my wife is crazy about. Install and setup were simple and fast. Began watching new TV in half an hour.
