I tested as well. With 1 sat I had 1 sat of fee and 100 sats I had 1 sat of fee. I used Minibits to send. Since I experienced higher fees on Radar I was expecting more fees. Overall for a beginner it looks good.
To me it seems quite unfair though to write a warning for Spark when Wallet of Satoshi and Blink advertise using Spark as well... In terms of UI adding a warning and an asterisk only there feels weird also. So I think removing all warnings for Spark or add a warning for all custodial wallets to make it consistent would be better. e.g.: I use Minibits with Stacker News, this is definitely custodial.
