Il miglior smartwatch nella sua fascia – preciso, resistente e completo!
Uso il Redmi Watch 4 da dicembre e sono davvero soddisfatto dell’acquisto. L’ho scelto dopo un’attenta valutazione, e posso dire con certezza che in questa fascia di prezzo non ha rivali. Le funzioni che utilizzo di più sono l’orologio, le chiamate (si collegano anche i contatti sull’iPhone senza problemi), il contapassi e le attività sportive – lo porto anche durante le sessioni di hydrobike, ed è perfettamente resistente all’acqua. La batteria ha un’ottima durata, anche con uso costante. Il display AMOLED è brillante, con colori perfetti e visibilità eccellente anche sotto la luce diretta del sole. Nonostante le dimensioni generose, è molto comodo al polso e non infastidisce nemmeno con un uso prolungato. Nessun problema di connessione con l’iPhone, anzi: è più reattivo di tanti altri smartwatch che ho provato. Per me è il miglior smartwatch qualità-prezzo attualmente in commercio. Non ha nulla da invidiare ad Apple Watch, se non il prezzo (molto più basso). Super consigliato! Scrivo queste recensioni dopo aver davvero usato i prodotti, sperando possa essere utile.

Bon produit solide et efficace
GÉNIAL très bonne alternative à des montres plus coûteuses. 2 semaines d autonomies, des programmes de sport et un podomètre efficace. Je fais de la course sur tapis le résultat est semblable à celui que le tapis enregistre. De plus la montre est de qualité et solide
