I had to read what that sleep suit was. The snuza is pretty loud when it actually goes off. The first buzzing alarm could possibly be missed. But the second alarm is pretty loud. This also all depends on how heavy you sleep or if distracted in other rooms. It's a loud alarm. However each person reacts and hears sounds differently at different times. It has helped us. And have been doing dishes across the room when it's gone off. Have been in a different room with doors open. It's loud. But there are other noises and distractions that could make you miss it. That being said we personally love it and it has got its purpose in our home. I believe it will help most sleep with more ease with the snuza.
