2 out of 5 eggsEverything works but GPS

Pros: Excellent chipset, fast, 3Gworks great on T-Mobile. Was impressed for the value I paid, overall decent phone for the price.

Cons: GPS does not work at all! It loses signal lock every 10 seconds, even if you don't move. I tried to exchange it for a new phone but their customer service does not respond to emails or return multiple phone calls. I was shocked, because the box contained a big card that says to call CCR for limited warranty 1-866-579-8436. I received no such service or response, now I am stuck with a defective phone. Blu also did not respond to any of my emails or calls. I am out of luck since Newegg will not take back cell phones.

Other Thoughts: Had I read the reviews, I would have noticed another customer had the same problem with GPS lock but mine does not work at all, it is completely unusable and this is bad for me since I drive often.

3 out of 5 eggsPhone works well, mis-advertised

Pros: Basic functions work well with the exception of the music and video players. The music player (playing AAC files) has hiccups. The video player would not play an H.264 file.

Cons: . The music player (playing AAC files) has hiccups. The video player would not play an H.264 file. Newegg advertises that this phone has a Stereo FM radio capability that I could not find. Phone is a no-show on the Blu website. Manual is of little use. Very little help available on YouTube for this phone.

Other Thoughts: The feature set cannot be found in another phone at this price. Since I need an FM radio in my handset I am looking at paying $100 more for a similar phone.

5 out of 5 eggsGreat Phone!

Pros: Very fast, great front and back cameras, customizable, and really just fun to use. Good buy, would recommend to all my friends!

Cons: None really other than that i had to switch service from virgin mobile - apparently they dont sell simm cards, and their phones just come with it inside them. Thats okay though, i switched to Simple Mobile for 40 a month unlimited everything and im much happier now anyways!
