I have the fp5 and flashed e/os myself. Im very happy with it. You need to flash it back when you want to sent it in (they have the instructions on there own page). Build Quality is nice. Repairs are simple. The price for spareparts is reasonable. And they really try to make a difference here and that is why i support them. Are they perfect? No? But who is? And you need to start from somewhere i think.
