Pros: small, handy, chic, good browser interface displays on the device enough, fast start within a few seconds, acceptable battery life (estimated 4 hours) and charging time (estimated 2 hours)
Cons: if the SIM card requires a PIN entry can lead to some Gefrickel until the unit records to disable the PIN code request, Firefox has nothing else where given, the initial indication of the browser page of the device was in Chinese (only Chinese characters, Choosing the right buttons or combo box pure feeling thing) but then discovered the combo box to change the language on the top right
Conclusion: Buy recommendation, at least for urban area, price bargain is suspicious
