I have the BLU Advance 4 and now the Figo III. I can say the Figo camera seems far superior to the BLU. I'd say it's worth getting just for the camera. It's not comparable to a high end phone, of course, but for point and click situations, even in low light, the pictures are not bad. The phone itself feels cheaper than the BLU, like it's made of vinyl. We'll see how well it holds up.
Note that the Figo uses micro SIMs rather than the regular SIMs of the BLU, if you upgrade. I used a template from the web to resize mine. It worked ok when transferred to the Figo.
The only issue I have found with my Figo is the display/touch calibration is a little off. Maybe there's an app to correct it.
Otherwise it's a spiffy little unit.
