TL;DR: At around $80, it’s hard to beat the image quality this projector delivers, and my experience with customer service was fantastic.
Pros:
If you spend any time looking at budget projector reviews, you’ll probably see the Happrun H1 recommended frequently for content and even gaming (for it's relatively low input lag). The color reproduction is surprisingly good for the price, and its native 1080p resolution provides plenty of detail for casual viewing. My experience with it has been very positive.
What impressed me even more was the customer service. My original unit was a gift and eventually developed some issues. I couldn’t get the original order number from the person who gave it to me, but support was still able to verify the age of the device and approve a warranty replacement within the two-year warranty period. The whole experience was excellent and gives me a lot more confidence recommending this projector to friends looking for an inexpensive option.
Cons:
It’s not especially bright. I’d really only recommend using it in a dark or very dim room. That said, the color quality and ease of use make it a great value if that fits your setup.
The fan on my unit was also fairly loud, though it never bothered me much in my use cases (mostly bedroom viewing and group events). Finally, focus can get a little soft around the edges, which is noticeable if you’re trying to use it as a PC monitor. For movies and other video content, I rarely notice it.
Overall: For roughly $80, the Happrun H1 delivers remarkably good image quality, and my experience with their customer service was excellent. It has the limitations you’d expect from a budget projector, but for casual viewing in a dark room, it’s an easy recommendation.
