Excellent in every aspect. With 3 power supply options (220V, 18V battery not included - 12V car lighter).
The only negative is the short cable for the socket, so an extension cord is required.

As others have mentioned, for a car it is very slow and may potentially cause the motor to break faster.
However, for bicycles, balls, and small tires in general, as well as for pressure checking, it is excellent.
Certainly, for this price, it is worth the purchase.

Replaced a functioning Dune HD Smart B1 after 10 years. I am very satisfied and the built-in library is very convenient. Note that it is mainly intended for users with local content (USB or NAS) and is not the most suitable for streaming (e.g. Netflix, although it includes it as an app). Personally, I have everything on my NAS and it plays flawlessly. You can also install the Play Store with an official firmware update. See review here: http://mediaplayers.gr/zidoo-z9x/

Update 10/8/21:
I continue to be very satisfied with the device. Many firmware updates have been released during this time, which have fixed or improved several things. You can also check here: https://www.mcbluna.net/wp/ Overall, I recommend it to anyone with a library of movies and series. For streaming, there are better and more economical options.

Update 23/9/22:
Everything mentioned above still holds true. Zidoo consistently releases new firmware with continuous improvements and additions. https://www.mcbluna.net/wp/zidoo-model-overview/zidoo-z9x-firmware-download/

Άμεση σύνδεση με τα χειριστήρια χωρίς input lag. Είναι λίγο ογκώδες αλλά σαφώς δεν αποτελεί πρόβλημα.
Σημειώστε πως δούλεψε και σε Steam Link μια χαρά.
Προσοχή όπως είπαν και οι υπόλοιποι να έχετε τους κατάλληλους driver. Προσωπικά τους είχα ήδη στα Windows10 χωρίς να το ξέρω και δούλεψε άμεσα.

User here for 1 month on a device with BT 4.2 where they work perfectly fine.
Almost complete isolation of external sounds. I am satisfied with the sound quality and the battery is excellent in combination with the charger.

The hard buttons are negative and they also become tiring after prolonged use.
In true wireless, I believe this is the most value for money option at the moment (I got them on sale for 80€).
