          Comments about Studio 5.5 D610A 4GB Smartphone (Unlocked, Blue):

          I use it as a phone and a tablet. The battery is pretty good but could be better. Only has 4GB of space so I suggest at least a 16GB micro sd to go with this device.

          I like that it works off 2 sim cards as I travel overseas sometimes and you can buy a pay as you go sim and switch sims.

          The audio quality is great, I do use it off speaker sometimes with TuneIn Radio sitting on my desk.

          I gave it only 4 stars because it could do with say 8GB or more of internal memory. maybe the next generation will correct that.

          The phone is very responsive and fast.It is not a Galaxy Note but a very good inexpensive unlocked replacement.

          I would also suggested an external battery for airplane travel and such so your not killing the battery when using it as a tablet.

            Comments about Studio 5.5 D610A 4GB Smartphone (Unlocked, Gray):

            I always wanted to buy a smartphone that I can afford. For my need this device is perfect. It has double SIMS that I could use this phone when I am outside the US. I could control my usage and save a lot from service providers with out a contract.
            If I use the web it uses it depletes the power easily. Although, battery last my one day use.
