First of all, this device is just a crossword game, nothing more. With that in mind, I want to share some general design tips. light doesn't work. Well it's a bad block. OK. I live in Spain. It is neither easy nor cheap to return the device to fix this problem. OK. No light.2. The screen is too bright, it reflects the light like a mirror, ie if you don't use a light (I have to assume) it's impossible to read anything. Contrast adjustment is available but doesn't help in this situation.3. It's huge. Thick, like a cheap device, not otherwise. But it works fine. From a gaming point of view, I have to admit that my English is far from perfect. but. The clues are very cryptic, short and difficult for a non-English speaker to understand. I'm not mentioning this as a downside, just a tip for other non-English speakers who, like me, want the device to practice the language. Will i buy it again? Maybe.
