MonBaby - anyone have one? Reviews?

My one week old had a choking incident and now I'm terrified to sleep. I want it buy a device like the owlet but the owlet is a lil out of my price range. I came across a post about the MonBaby and was wondering if it's worth the purchase? I have not slept in almost two days maybe 30 mins here and there and I know I can't keep functioning this way. Any reviews or pros and cons about this product would be appreciated.
