I am using a borrowed Starlink RV unit on Anegada right now. I have done some performance comparison with it and my Digicel cellular service. My observations:

Speed: OK to Super. Using the Starlink app speed test, I have seen download speeds of over 200Mbps. Most tests show 20-30 Mbps. At the moment, I am seeing less than 10Mbps - still more than enough for TV streaming. I normally get 20-30 Mbps from by Digicel cellular, so no real difference now. I am guessing that the huge variation is speed is caused by variation in satellite availability. I expect this to improve when they start residential service here.

Latency: 50-100ms, about the same as Digicel.

Outages: Quite a few instances of "NO SATELLITES" or "NO SIGNAL RECEIVED". I expect this to improve when they start residential service here.
