We’ve only had it a few weeks but no problems at all.

We can watch TV outside any time of day — the brightness is incredible, even in direct sunlight.

Definitely worth the price. Everything feels premium and it's become a daily use item for us.

We were looking for something between basic and pro-level — this hits the sweet spot.

The 32-inch screen is perfect for our small covered deck. Very clear and sharp display.

Seems well-built. Looking forward to testing it through the season.
