Genuine Baby Monitor Medical Device

To those expecting a baby soon:

I won't say anything negative, so I recommend purchasing this as a way to buy peace of mind.

I gave birth at a university hospital. During that time, I had more bleeding than usual, and on top of that, I experienced after-effects from general anesthesia, which prolonged my hospital stay. Even after being discharged, I couldn't move my body as I wanted.
In the midst of this, with my first child and no room to spare, I became very anxious, but this product truly saved me.
The reason I purchased this was precisely because it was used at the university hospital where I gave birth.
As written in the instructions, it comes with two plates. You don't need the second plate until your baby starts rolling over.
Once they start rolling over, you use both plates. However, in my case, I moved out of the baby crib once my baby started rolling over, so I never used the second plate at all, and it is brand new and unused.
Please understand that I did use the first plate.
Also, although the photo shows it being used with a baby crib, you can also use it with a futon, so please don't worry.
I used it with a futon when I was at my parents' house.
It requires batteries, but I will include new ones.
It's quite expensive, but I believe it's a purchase you definitely won't regret.

If you have any other questions, please feel free to comment.
I am also open to price negotiations.
