from 219 reviewsHeat-up time was faster than our last unit. Happy so far.

Gets the job done without any fuss. Quiet and consistent.

Works great during cooler evenings. Still holds temp steady.

Came across this model through a friend’s recommendation.

The control panel is easy to use and understand.

The installation guide was decent. Would recommend to a friend.

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.
