Query: Good price, small size, necessary item for 2-story home; disappointed 1-time use though

The price for this was great and the size is small so fits easily under a bed or something. This is an absolute must for our family in a 2-story home. I was disappointed to see it quotes a 1-time use but I hope I don't have to ever use it so understand.
