It’s a Chinese brand, Mike. Fairly new to the market, so they don’t have the reputation of the traditional brands, like Samsung and Panasonic but then neither did LG (originally Lucky Group!) when they started out.
I’ve come across them in hotels the last two years and wasn’t impressed but they do low and and high end models. The low end seem to get ok reviews because they’re cheap. The high end stuff does seem to use the latest technology and get good reviews on the whole.
As an immature brand, a good warranty is comforting to see.
I’m tempted, but I’ve a good Panasonic which is serving well and wouldn’t want to scrap it for a slightly bigger screen (no room for more) and latest tech.
