Works as it should
Works as it should. Original one lasted 10 years. This was a replacement in a pickup truck to run a 12volt DC pump to fill an auxiliary diesel tank.

10/10 Would Recommend
The timing is almost exactly 15 minutes at full turn, but more importantly, it will countdown with even the smallest turn. The problem I had with the others is that they would turn on with a small turn but the timer would not countdown, so the light would just stay on forever if you set it to less than 5 minutes. This one starts with even 1 minute so the light won't get left on anymore.

Ordered two of these, first one failed in three days, the other one failed two days later. Returned both and purchased more expensive ones from electrical supplier. Timer would not shut off after time finished.
