Pretty flat. The seller in the site chat gets in touch and answers questions The device itself is well made. They take up little space, but in the economy, no, no, yes, they are needed. Good thick plastic. I received this device the other day. A protective film is pasted on the control panel and screen. All without gaps and squeaks. Reached me pretty quickly, within 20 days by China post (free) Size, not big. The box with it (whole, high quality) was packed in a paper bag with a film inside. Can be weighed according to tare weight. Has 3 weight units.
The screen is well readable.
