Works, but for how long?

Works, but for how long?
This resistor kit works and gives back the full range of fan settings for my '09 Tacoma. This is the first time I've purchased from this seller so hopefully this one lasts longer than the previous ones I've used, but so far it works as expected. This is the 3rd time I've had to replace this thing in 14 years on this truck, so I'm not hopeful that this one is going to be the last. The OEM one lasted about 10 years, these third party resistors usually only last a year or two. I've resorted to installing these things with quick connectors (pictured), so the next time it burns out I can pull the old one out easily and I just have to crimp the connectors onto the new harness. If you're replacing this in your vehicle chances are you'll be doing it again someday so it's worth making life easier on yourself in the future.
Thank you for your feedback
