5 out of 5 eggsWarranty

Pros: The warranty on BLU phones is one year from date of purchase NOT 30 days as posted by NEWEGG.

Cons: It took over an hour to talk to someone at tech support so I suggest the email route if you need to contact them.

Other Thoughts: The rep was an English-speaking American. Very knowledgeable and they are based in Florida.

4 out of 5 eggs

Pros: It's more responsive than my old phone (an amaze), supports two sim cards, and has a decent amount of storage space (but you'll probably want an SDcard anyway).

Big screen, doesn't choke on videos like my old phone. :D

Cons: Only has 500MB RAM, would be nice if it had at least 1GB; it's a bit annoying when your browser closes while browsing Facebook.

Camera flash only has a single level of brightness, which is plenty bright, but would be nice to have. Also, camera has no physical zoom, only digital. And no capture button.

No search button. Something I often reached for after switching from my Amaze is the search button next to the home button. I miss being able to search documents, contacts, etc., without having to first search for the application's specific search button, if it even has one.

Other Thoughts: Overall a nice phone. Hopefully when/if they upgrade to Kit Kat, memory usage won't be such a big deal.

Power button is on the right side, rather than the top. Often hit it by accident when holding the phone in my left hand, like it better on the top, myself.

Audio quality isn't quite as good as the amaze (probably lower quality speaker), but the headphone jack hasn't been damaged on this phone like it was on the amaze (dunno if that was a manufacturer defect or what...) from just inserting some headphones.

5 out of 5 eggsExcellent for the Price

Pros: This is another excellent product from blue. I bought BLU Life Play L100A a week later. However Dash 4.5 style seems to be better for me and how you feel in your hands. I really like every feature and specifications of this product including Jelly Bean OS. Overall an excellent phone for the price and its very practical.

Cons: Only one. Display is not excellent if you are viewing it from an angle. Excellent with 90 degree view so read the specifications carefully.

5 out of 5 eggsNOT dual band wifi, they fixed the info

Pros: this phone has great specs: quad core, 1.2 mhz

Cons: newegg had this phone on its site for months saying it had dual band wifi, and it does NOT. they finally corrected that after my emails

Other Thoughts: another waste of time and money. i have not received it yet, but will promptly refuse the order, based on the incorrect specs. not blus fault, newegg sales team needs to get its act together.

5 out of 5 eggsExcellent for the Price

Pros: For the price this phone is incredible, the 512mb ram has not been an issue at all (I set my phone to kills apps so they don't run in the background) The wifi is speedy and I can con confirm the 3GH+ works and is fast as well (faster than my buddies 4G who uses a S Galaxy 2). I use straight talk and ordered a at&t compatible sim card. Battery is confirmed 2000 mha.

Cons: Not a traditional Phone company. Not rooted. Case is tricky to pop off. Sims slide in length wise. No market for accessories (yet).

Other Thoughts: It is a incredible competitive product for a HUGE fraction of the cost. I came from a single-core 800 mhz android 2.2 and the difference in performance is day and night. If your budget is small, but willing to spend a little then don't hesitate and make this purchase.
