Leak Sensor Recommendations?

Yes, I just got mine today. No pull tab, they were already activated. I only paired one of them, but it has a newer firmware version than my older ones and the battery reports 200%, as detailed in this thread: Battery reporting 200% (Linkind devices)

Update: Configure + Refresh, while pressing the button, shows the correct battery value. I've paired 2 of my 4 and they both show 100%.
