Bought bracelet at sale price, wear often. Clasp is very secure, no issues at all. My bracelet is full with gold Michael Hill charms and clasp still holds without unintentional opening. I do have a safety chain on my bracelet for extra security. The previous reviewer must have a faulty clasp mechanism and should be pursuing a replacement bracelet from Michael Hill customer service. I am a frequent buyer of Michael Hill jewellery without any issues. My purchases are all sale items.
