## Customer feedback

Aggregate customer ratings are positive overall, with the available distribution showing four- and five-star ratings. The small sample offers limited insight into performance or fit, and no written customer feedback is provided to explain the ratings. For AD5X buyers, confirm nozzle fit separately and treat the ruby-tip durability claims as manufacturer claims rather than customer-established results.
