Levana Oma+ Reviews/Thoughts

So I snuck a peek at my registry and someone bought us this baby movement monitor- I didn't even know these existed!! It seems like it could be a good thing to keep peace of mind or a bad thing if it falsely alarms and wakes up us and baby. Has anyone had one of these? What do you experienced Momma's think??
