how do i go between or even know when i am in the different stages? it says go "up" and "down" but i don't see how to do this.

Yes I went through it. Look to the device side way. Press one button and you will see it stay a bit down compared to others.

Do the settings stay the same between power cycles? Once I hang this in the attic, I will only have convenient access to the extension cord.

This item does not change cycles and it was returned because it did not work as advertised.

What is the warrantee if it doesn't do the job?

Ours worked fine. answer possibly on the paperwork enclosed with product. If not contact Amason…

Worked perfect for us

Honestly have no idea why there are so many bad reviews on this product if you read and follow directions this thing works amazingly! We got this because we had about six bats living behind some shutters on the front of our house we put this thing right under the window in front of the garage and it worked it one night! Here’s a little back storey last year we had this same problem but with double the amount of bats we had to pull the shutters off our house and wait two months to put them back on all while the bats circled the house every night trying to find a way back it, I wish we would have found this product last year it would have saved us so much time! Highly recommend this product!

Stay Away from this supplier

If I could, I would have given 0 stars. The item received was faulty and practically impossible to contact the supplier. Please stay away from this supplier.
