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 analyses reviews to verify trustworthiness.
This is pretty handy for tracing images from your screen to paper - I’m really enjoying it. You just have to remember to brighten the screen, and you can zoom in on an image to get exactly the size you want to trace. It doesn’t need the app.
The product itself seems to be good. However, the directoons are in chinese. Also the website is useless. All the language is in chineseand unsure how to use it. NOT user friendly App. There should be an english verision. The app would also nit diwnload onto my phone.
It takes a bit of getting used to. But I enjoy it. Compact, easily stored, easily assembled. The app mentioned in the instructions doesn't exist anymore. Luckily, the app is not required. Still, it would have been fun to play around with it.
