I think this is a good price for the product. I believe their 14" TV alone was $149. This also has the DVD included. To me that's a plus. Plus this has free shipping.
This may not be a name brand, but my belief is that most of these type of products come from the same factory and various names are stamped on them.
Reception of quality and number of channels with an Over The Air television often depends on location, location, location. I live 20 miles outside a major city, in a valley surrounded by hills. With the antenna included in the TV only version I can pull in about 10 channels. More if I use a more powerful, but not amplified antenna.
Though I've not tried it on the Trexonic TV, it has a HDMI receptacle so that a Roku or Firestick can be attached to provide more possibilities. I simply power those devices with a power bank.
As with all TV of this type that I've come across the picture is best viewed straight on.
I think what it comes down to is if you can envision a use for this. I use my TV when spending time out on the deck, or in the kitchen while involved in a lengthy project, and mostly in my garage while I'm working on something.
My reason for buying the TV was due the frequent power failures. Seems whenever there are major storms I lose power for a several hours. (That's why I keep my laptop fully charged so I can always watch a DVD if without power.) I also like having this available to use in the basement when there are tornado watches/warnings.
There are less expensive and more expensive models of portable TVs. I like that these models are rechargeable. That suited my needs.
I never put much stock in most reviews of so many products. I find after reading some reviews that people may have unrealistic expectations of a product, or not be clear on how to best use a product, or may not handle a simple learning curve.
