The bargain! 4

Update 17 August 2014: the phone has suddenly made bugger. The keypad wrote alone, some keys no longer met and the photo or music player device were setting out alone then blocked. Even the factory restorations have changed nothing. Back against reimbursement accepted by Amazon. An isolated case after only 5 months of use? Hopefully ... I'll try another Chinese brand to see (still with Amazon, to be quiet)

Verdict after 3 months of use:

This MySaga C2 runs Android 4.2.2. So enjoy all the services and applications through Google Play (after the first update).

Equipped with a Dual Core processor clocked at 1.2Ghz; ROM: 4GB (expandable to 32GB via micro SD); RAM: 512MB; 2 SIM card slots (standard), and a 5.0 inch screen with a resolution of 960x540 (one small concession to smartphones 3-4 times more expensive. But given the size of the screen, and the distance from natural reading I hardly see any difference with a 1280 x 720 HD screen of 4.7 inches). And it's still better than the 800x400 proposed definitions on most phones 150-200.
The display is not scratch resistant Treaty (Gorilla glass), so not as strong as higher-end glasses (required protection), and the viewing angles are quite small. But this is obviously related to the price of the device, and does not constitute in any way a crippling defect.

Small bonus, the phone comes with 2 original 2200mAh battery, only one already offers a beautiful autonomy of 2 days in sustained use!
By cons, it takes 4 hours minimum to fully charge if the battery is discharged (like many smartphones ...). But the 2nd battery troubleshoots well, just in case.

Note the relatively high weight: 170 grams. This can quickly become tiring when used outstretched arms, or lying on the sofa for example ...

Finishing, responsiveness, part phone, audio-photo-video connection, wifi reception, 3G, etc., are more than correct, no complaints. Even surprising, considering the price of this mobile (96 ships, dated 1 March 2014). I really do not expect a product of this quality.
One can sometimes notice some bugs thrust multitasking. Including certain websites a bit "heavy", which crash the browser, it simply restart to fix the problem.
I installed Opera Mini browser, which it almost never plant (very light), which can also save 90% of data. Useful if you do not have a flatrate.
I also installed Firefox and Google Chrome browsers, as Flash Player (searching the Internet, as more available on Google Play).
Flash Player allows you to view the websites "animated" as a computer. It works with Firefox browser or the original, but also other browsers available on Google Play. Super convenient, as some sites are virtually useless without Flash Player.
The FM radio lets you listen to the radio without being forced to go through the Internet, unlike many smartphones unfortunately.
I would describe the fluidity / medium reactivity. But it's still nice and fun to use is real, and there is no heating problem regrettable, and whatever the use.

The seller "Three-Color" has been very responsive (delivered in 2 business days), and the package is shipped by Amazon (thus with the quasi-free return if applicable).

MySaga short it is a real good surprise, that it would be wrong to deprive yourself.
