"as good as I've tried..."4.5 starson by ericwhansen
Pros: I ran over my captivate, being able to use my accessories (batteries, chargers) I already owned was a bonus. I prefer the mezmerize over the captivate mostly for cosmetic reasons (other than the added camera flash). It seems to be a bit snappier.
Cons: I wish it had the internal 16GB sd and an external sd slot (like the captivate). 32GB microSD cards are still a bit pricey. Slightly flimsy feel to the overall build.
Summary: I've gotten nothing but pleasure from this phone so far. No technical issues whatsoever and I've had plenty of problems on other handsets.
