It depends on your transaction size: Anything above 1 sat/byte is unnecessary, see
Fees are low, use this opportunity to Consolidate your small inputs!.
For $0.17, you could have made a 2.5 kb transaction, that's 14 inputs (non-SegWit) and 14 outputs. If your transaction was smaller, you paid more than needed.
