    I purchased this TV to work with my firestick to go on my garage. It has a really nice picture and is perfect size for my garage. This is the perfect TV for my home gym.

    For the unheard of, & great $119 price point, I couldn't be any happier being the proud owner of a new 40" LED 1080p Insignia TV! Although I haven't taken it out of the box yet, & probably won't until I've squeezed out all the remaining LED PIXELS of the old 27" LED 1080p #### TV I still have in the bedroom since 2012. But I know I won't be disappointed & will update my review when I do. Thanks Best Buy for the outstanding customer service & the amazing deal I got the TV for!

    I ordered for my 92 yr old Mom. A great price for a known brand. Delivery was on-time and set up was great…the technician knew it was for my Mom, so he kept in short & precise, just the basics. Of course, she still has it and the picture is very good quality w/ pixels!

    The tv is so clear and is a good size . I bought it by mistake thinking it was a smart tv. It’s not but it still gets the job done connected to my Roku device. Definitely a good choice for a bedroom

    A great unit, good size, fantastic picture, and so vivid. The sound is a LITTLE bit weak, which can be mitigated by turning the volume way up, or adding a sound bar, which I did, via the output jack... no big. I’m quite satisfied with this tv, and you can’t beat the price!
