Review: Easy setup and looks very good - Got this for my office. It is so easy to set up and the result looks very good and professional. We are just using it for wifi password display for guests, but it can be used for soooo many occasions. I am excited to find this little creative tool.
Review: Terrible product impossible to read - Terrible product. The letters showing g in the screen are fuzzy not clear. It reduces the font to the pont you can not read it. It only shows green screen in the background. It's impossible to read anything you write like intructions. Notices, anything you write in the screen is reduced to the pont you can not read it. There is no option to change the size of the font. It's so small that nobody can read it. Don't waste your time and money on this product suport can not help you because that is the way it was designed

### ⭐⭐⭐⭐ Variety of uses
*by K***T on December 13, 2024*

While there is a variety of uses for this, and it does look pretty good, the thing I find frustrating is that for how much it costs, the annoying flashing between resetting the screen is a little bit much to me. Hence why I only gave it 4 stars. I also missed the size, 4 inches isn't a huge screen and for the cost, I don't know, personally I'd rather just pay $20ish for someone to print and laminate a nice looking sign. I had intended on using this for payment options when I do craft markets instead of the laminated sign that I have. The long flashing between screen changes is a major turn off to me. Even if I just left up one type of QR code payment, when I needed another it would be annoying to switch between screens. I am still on the fence about it, but I might have to find a different plan for it's use. There are a lot of options to use it for, I'm just not sure any of them will suit my needs.
