Review on ⚡ Cooper Bussmann NO 263 Number 263: Reliable and Efficient Electrical Protection Solution by Jon Garcia

Stamped from very thin copper they are very difficult to install and remove at the end of the fuse without damaging the adapters, the fuse or personal injury. Also, neither these adapters nor the fuses are perfectly cylindrical, so while they probably make enough electrical contact with the fuses to be used for lower current connections, the fuse holders I've tried them with aren't very good at making those Keep fuses safe with these adapters fitted. I threw them away and used some old fuse adapters that were much thicker and made a much stronger connection. It's a mystery to me why they got so many positive reviews for Revain.
