Bi metal switch thermostat, how reliable?

I wanted to use this on a fan, but wanted to know how reliable they are. I typically try to keep things simple to reduce the chances of failure, but this appears to be simple enough.

It's a plain vanilla bi-metallic switch; datasheet. 60°C+/-5°C; Reset 40°C +/-10°C, a bit loose.
I don't find them that reliable, as they are a mechanical thing and moody about their temp trip point. They need a cap across the switch, so the contacts don't arc stuck.

I would consider low-cost ~$8 eBay electronic temperature controllers (china). For a few bucks more, they are adjustable and LED display of temperature. Like the TM-900.
