I pulled the Dual one off the other day and held the single and dual up into the sunlight and watched them spin. At various times the dual wouldn't spin up the fan when going into the light vs the single would spin everytime. Now the single was a little noisy which is why I replaced it to start with but it appears the fan on it did spin up everytime AND seems to spin faster. I called Acurite's support and raised hell about them not supplying me with a return shipping label for something they should warranty. They finally gave in and said they would refund me the cost of it just supply a shipping label receipt. I told them that if they return the original saying it was fixed and it still wouldn't work that I would request yet another return label cost and the full cost of the item cause I'd send it back and say the hell with it. I have the single on right now and it seems to be doing ok but again its just noisy.
You really gotta get serious with them and over the phone before they budge which doesn't say much for them as a company.
