Yeah just need to look on reddit etc to see what users are experiencing. Alot of Downtime and speed issues and disconnects. Starlink is FAR from being stable this time and for $159 NZD a month + $799 for the hardware that definitely isn't cheaper than fibre. I've since cancelled my pre order for Starlink and got the $159 refund
Starlink was never intended to be cheaper than fibre - its always been intended to give a much better service to remote/rural users who can't get fibre. If you can get fibre (or even great VDSL), then you definitely should!
Starlink is currently still in 'beta' testing, originally titled "better than nothing". Though its imperfect, most users on Reddit are very happy with their performance - just lately getting up to 400mbps. Different regions may have better/worse performance as they iron out networking issues with each ground station etc.
