User reviews

Köksal Başar (ID: 000000af3ec9d3b6) Voted 5 ★ - Updated 12/14/2024 It will definitely come in handy. It's the best I've used.

emanuele bortoletto (ID: 0000002465c1b84e) Voted 5 ★ - Updated 06/17/2024 Molto utile, si avvicina moltissimo alla visualizzazione reale nei dispositivi. Crea problemi con il debug dei siti in alcuni casi, conflitti con i file js e altre estensioni del browser, ma è comunque molto utile

Allan T. Rasmussen (ID: 000000690e34c263) Voted 5 ★ - Updated 06/12/2024 Simply the best one out there. Easy and reliable. Awesome features and great updates

Henrique Silva (ID: 000000d359665dc6) Voted 5 ★ - Updated 05/31/2024 Top demais! Os modelos gratuitos ajudam bastante os desenvolvedores, e se quiser pagar por mais modelos é bem barato! Super Recomendo!

Samuel Archibong (ID: 000000c4c29fbe1c) Voted 5 ★ - Updated 05/07/2024 I love it. It gives me the screen size I need, makes it more user friendly that the natural devtool for responsiveness.
