I am a Google Fi user, the Pixel is by far the best phone I have ever owned, and I have zero complaints so far. To contact customer service, if I ever need to, it takes less than 10 seconds. I almost always have service, if I don't have tower service I swap to WiFi and have the same and full capabilities. I dont have any issues as it stands, though I have been using Google products since 1997 and might be a bit of a fanboy... =P
