Arrived on time. They were the exact replacement for the old one which had expired. Didn't even have to change the base or cord. Unplugged the old ones and plugged in the new ones. Very pleased

I was glad to find an exact replacement for the old alarm, which began incessantly beeping when the CO2 monitor aged out. I had forgotten that these things last only 5 years from date of installation (or whenever you take the blue cover off). But given that the wiring was the same, it was just plug and play to replace, so pretty easy to do.
