First I ordered (and received) the device, then I got to read the comments and reviews. Strange, right? But it happens to me. Very upset that the purchase will be useless. But, apparently, I was lucky, like one of the other buyers. Inserted batteries - everything works. The screen is not red, but blue, but everything is perfectly visible. And the build quality is ok. Nothing creaks, does not vibrate, does not dangle. It is pleasant to hold in hands. The truth for some reason shows half the charge on new batteries. But, perhaps, this is because I bought the most inexpensive batteries in the fixed price. I'll see how long it lasts
