I've found them to be excellent the few times I've contacted them. They even debugged some networking issues within a few hours when my phone was having trouble switching to a Japanese data network, all while keeping me updated on their progress. The Fi vs every other carrier delta is the primary thing keeping me from an iPhone. I've been a bit less impressed with the hardware reliability of the Pixel, and Android's software experience isn't quite as good as iOS'.
