To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
I have purchased two of these units for R.V. use and one came damaged (which was replaced promptly) but the company was quite hesitant to simply refund. The audio speakers are very low grade for the money. Picture quality is above average for a 12v unit.
Customer service was great. We had a couple burn out on us when connecting to shore power or generator power. The TV works great but it will not handle any power surges. I would suggest completely unplugging it when hooking up your RV power. Even when the TV is off and plugged in it will burn out if there are any power surges. The odd part is the fuse that came with the TV cord never fried but the TV still did. It should have built in power protection but if you are careful with that part it is a great TV.
