I saw a lot of negative reviews, mostly related to less than promised useful life. I'm happy to say that when I activated mine, it had the full 24 month life displayed. Now to find someone that sells the "hibernation case" so that I can get more life out of it.

Ordered the items on the 26th of August and they showed up on time, no issue there. However product box clearly states activate before June 9th, 2022. I called Honeywell support and they said they can't guarantee the device will work properly since we are past the activation date.

Device works as designed. The issue is that it has a short shelf life. The meter is supposed to start its countdown from 24 months, but the one that I received only had 16 months left when I activated it.

We have several of these O2 monitors in use at one time. They work fine and alert when supposed to but they all went bad at varying times and all earlier than the purported 24 months. We started 5 of these at the same time and all had the same date on the box. When they expired, a couple were within 40-60 days but 3 were showing 5-7 months. Three others were still in boxes and never activated but they were all bad since they hadn’t been started within the 6 months of the date printed on the side.Be sure to turn these on within the 6 months as mentioned in the instructions for shelf life.

Great little safety monitor. Not happy with having to buy software to see live 02 reading.. But if you hit the button you get last value so that works as well.
