When my bin arrived at Christmas I felt just 1 strap was insufficient for the 100 ltr model. My thoughts have been validated as now just a few months down the line, the door has buckled badly. But purchasing a second strap, I now think I have solved the problem. But for the price of an extra strap when new, it’s a bit false economy by hotbin, please consider a second strap as standard ( as supplied with the 200 ltr).
