Bloody hell that's cheap.
It is. I am curious to see the build quality and responsiveness, but my expectations are not very high.
So my BLU Studio 5.0 HD LTE arrived. I must say, I am impressed by its initial performance. The screen is decent, comparable to 720P smartphone screens I have seen. The phone is plastic, but the build quality is just as good as other Android phones like the Nexus 5. The various bands work as advertised. I am on T-Mo, popped in my SIM and was pulling 45Mb on LTE. Performance is good, at least switching between apps and such. Haven't tried any games. Tested out Netflix, looked really good. Call quality is just as good as any other Android phone I have used. I haven't tested the camera yet, and can't comment on battery life since I haven't used it much.
My verdict is that it is worth every penny of its $170 price tag, considering that is for an unlocked, unsubsidized phone (still a thing here in the US). It comes with a charger, silicon case, screen protector, and headphones. A very good deal indeed. I am going to order one of their Windows Phone models today to test that out. They don't have a Windows model that supports LTE, but that is okay since it is just a test unit.
