Very nice for the two Champ devices was the functionality despite the small mobile phones.
The Star is 3 to 5 mm larger than the Champ models in height and width.
The Star 2 is narrow as the Champ models, but longer by 10mm.
In Star 2 of built browser is better than the Star 3, partly because of the zoom function. For this is the Star 3 Opera Mini comes with better presentation and zoom possible.
Only the Star 2 has a position sensor and Google Maps.
Dictionary German <> English is installed at Champ 2 and 3 at the Star and tip.
Micro-USB port is the Star 3 below and not concealable. Star 2 and Champ have a cover.
Only when Star 2, the micro SD card is the side under a small cover.
Overall, the Star 2 feels something noble as the Star. 3
The Star 3 is only a slightly larger Champ 2 with Wi-Fi.
The Star 2 + 3 I would anytime prefer the Champ Deluxe (C3310), REX 60 (C3310) and Corby (S3650) for WLAN and camera.
This Star 3 is actually the same as REX 80 (also S5220).
