Review on SF139E SEFUSE Thermal Cutoff Degree by Srinivas Johnson

Pros: 1. It successfully replaced a blown fuse in the Instant Pot Duo. It comes in a 3-pack. Cons: Ordered from us for the first time in December and successfully revived the Instant Pot (which my wife uses 2-3 times a week). It was great that the solution was so simple and affordable. BUT seven months later we are already on the last of 3 backups. I'm not sure if this is due to the quality of the product itself or if it's because I don't solder it (just twist it). The original thermal fuse that came with the pan lasted two years. The first of this pack lasted 6 months. The second lasted 6 weeks. Just insert the last of the three today. I hope the third time is the charm.
