I bought this TV back in June 2018 and it is money well spent for a 4K UHD tv. I‘m still totally amazed at the quality and the great features of this set.

In Sceptre I Trust

While the brand is lesser known I took a chance on it during my first ever tv purchase 4 years ago. (40” 1080p). I am even more pleased with the brand on my second purchase. (55” 4K) Several features such as the MEMC 120, the 4 hd ports, custom source labeling, and the ability to link the remote to multiple devices go above and beyond. I wouldnt trade my tv for anyone else’s.The quality Sceptre brings for the price is unmatched. Buy a Sceptre, you won’t regret it.

easy to work

It took no time to program the TV the way that I wanted. Great picture and easy to maneuver around in using all of the functions. I admit I was nervous about purchasing this product but it has proved me wrong.

Great value in a 4K UHD set.

Although purchased about three weeks ago, I got it set up only yesterday. Being technically challenged, didn‘t get the settings right until this evening. I realize that settings can be more complicated and critical in a 4K set, butthought it a bit complicated and lengthy getting the right settings. Otherwise, I love the set.

Great TV

This is my second Sceptre. First one was a 50 in. Great TV also. Sound is not to good but all flat screens are that way. No room for a big booming base speaker so plan on buying a sound bar. Hope to get a lot of years with this big old 55 incher.

Excellent picture

Easy to hook up.....great picture even from a standard DirecTV receiver (no hdtv).
vonna32 2017-03-14

Great Quality

I received my 55 inch Sceptre 4K TV last week and I absolutely love it. Great price and great quality. I would purchase again...

Great Picture!!

The colors and contrast are great! Even better than my old sony!
Avery66 2017-02-17

Great picture!

I bought this as a warranty replacement for my X505BV which got damaged in shipment. It thus far has exceeded my expectations. Awesome picture and easy to use.

Great TV

Great picture and easy to set up. I was worried about the sound but after getting it the sound is better than my 47" Vizio with forward facing speakers.

Great TV Experience for 4K...

My Papa bought me this TV in replacement for my old one. And to my big surprise it was not I‘ve ever expected so far, it‘s way beyond my expectation... I was amazed by the finest texture of picture... And it was awesome, delivering from my 1080p source of movies from my hard drive.. Thank‘s SCEPTRE for making this innovative products brought to life....

Great intro into the 4K market

I purchased this TV at the local Market this past Black Friday as the sales price was too good to pass up for a 55 inch 4K television. I have never owned a Sceptre television and tended to stay with Samsung. I am glad I made the change. For the price the visual quality is simply excellent. I have been running 4K on it through DirectTV‘s channel 104, Youtube and Netflix. The picture is outstanding. Great color, contrast and detail. A huge step up from my older Samsung 50 inch 720p DLP tv which now resides in one of my son‘s rooms. Setup was extremely easy (and thank you for the free screw driver). On screen controls are simple and straight forward to use. I tweaked both the picture and sound levels to my liking and did eventually buy a soundbar to augment the TVs own sound. I could not be happier. Even the upscaled 1080p and 720p channels look excellent. Watching NFL games each week has been an experience in and of itself. What color and realism. Two thumbs up for this product!!

Great Purchase

Excellent tv viewing experience Exceptional Value

Great picture, poor sound

Pretty straightforward setup. Beautiful picture. Could not find a good sound setting that satisfied. Now using an external audio system. Closed caption font size should be larger to make easier to read. Could use one more HDMI input and another audio output. Reasonable price.
Frailey 2016-12-11

Awesome picture

We bought this TV on Thanksgiving on line. It is awesome and a great price
Snoopy96 2016-12-11
