Thanks for posting such a thorough, updated review, @Scottathew!
I’ve removed your referral code from the post. We need to limit referrals to our Referrals category so that the site doesn’t become overrun with spam referral posts. However, I’ve linked from your new post (above) to the post with your referral code so people can easily find it, and I’ve removed my own referral code from the official referral page so that yours is the only choice for Google Fi referrals.
Thanks again for the updated review and happy holidays!
