New relay users are often attracted by low multipliers or bonus balances. Long-term experience depends more on stability, model coverage, billing rules, incident handling, and refunds.
Current monitored examples such as YunDou, lingxicode, SudoCode, infai, toproutercn, right are useful for comparison, but top-up rules must still be checked on provider sites.
Four checks
Check supported models, pricing rules, status communication, and refund or dispute paths.
If a provider has only a payment page but no status notes or contact path, reduce trust.
Recommended strategy
Start small, test real tasks, compare transparency, and keep a backup endpoint. The best relay is not the cheapest one; it is the one you can verify.
