Great rings, wrong sizing
Perfectly as described, great rings and colours. However too big for me. But. Thunderfit offer free refunds without the need to return rings in case of wrong sizing. This no hassle return service is why I chose them. However Amazon have required a return of the rings to issue a refund. This is going to significantly delay the refund process, and organising the pick up is annoying as someone who isn’t home often. This is not as described and I feel a little conned. Even the packaging they came in reiterated the free refund with no need for return policy. I’m confused by the false advertising on Amazons part. Will be purchasing directly from Thunderfit in the future.
