Review on Muzata Hand Rivet Tool Nut Setter Kit: High-Performance Heavy Duty Thread Blind Riveting Tools with Wrench Nut Sert, 5pc Metric Mandrels and 100pc M3/M4/M5/M6/M8 Rivnuts, Complete with Rugged Carrying Case RK01 by Brandon Hayes

. held inside and not by nuts. After the first use it was clear that this tool would cause problems. 1. The handles are too short for the correct expansion of the inserts.2. The top of the tool is curved and split. (see attached photos)3. The back of the mandrel is deformed and will not function properly. (see attached photos) If I could return this I would, but as the returns window closed for me in April and I started using the product in May I ran out of money. Learn from me and DO NOT BUY THIS PRODUCT. I have been a certified Honda technician for over 12 years. I know how to use tools.
