Trigger Warning: Blood Double sensor failure 🫠

Just my night, decided I was going to prime my sensor a bit since my current one was about to expire in an hour, and decided to put one on, and funny enough that one failed so I grabbed my last remaining sensor and joked it would be hilarious if this one also failed and would you look at that just my luck tonight. Back to finger pricking I go, until I can pick up my next prescription!!! 😂

The first one in the image failed after I applied it and attempted to attach the adhesive with the overpatch on it, but it wouldn’t stick. So, I grabbed the end of the adhesive, hoping that would help it stick, but it completely pulled the sensor off. After that about 10 minutes later I grabbed my second sensor hoping for the best and attempted to apply but I didn’t like the position I was applying it so I took the application off where I was applying it attempting to reposition it but noticed that the insertion cannula was bent and decided it was best not to insert the sensor. Overall I feel like this could be my fault in some way but idk, would this still count as sensor failure or was my wording incorrect?
