Perfect Fit - 01/18/2012
Reviewer: Randall Goldman
Not having the ability to hard wire, I needed a unit that would be easy to install yet able to protect my family. This product fits those needs better than I expected.




Test button issue - 01/06/2012
Reviewer: Val K
When setting up the unit, the test button stayed depressed, then would not work at all. Seems to be a design issue - I didnt push *that* hard, but I did push with some pressure. I called customer service, and the rep was extremely helpful, with information on the issue. I told her the red light was flashing, but the test button did not do anything now and was staying depressed. The company seems to genuinely be concerned with consumer safety, as she quickly offered to provide a replacement for me even though the power light was indicating the unit was working, since it would not be testable each week as suggested on the packaging.

eAccess Response:
We are sorry for the confusion on your orders. You had placed 2 orders and we tried to help by saving shipping costs(which were credited)for you and combined your orders. This is where things got mixed up. Again, we are sorry about this.
As to the manufacturing issues, we can contact First Alert to alert them to these complaints.
