"My wife, 67 years old, and I, 70 years old, love to swim in our local lake in summer. After our children raised concerns several times about the increased risk of drowning, especially for older people, we put some thoughts into how we should solve this. We discovered Restube beach when doing research for suitable safety devices. Since then, this simple and ingenious aid has been our constant companion in the lake. We, but also our children, are convinced of Restube, because it has brought an enormous increase in our safety."
