My next door neighbor and I (both over 67 years old) put this together in a matter of hours.
It went together with virtually no problems. It was so easy I wish all of my projects went as well.
We hope we will never need it but feel so much more secure having it in our home.
The main reason that we chose this shelter is that it can be assembled in place.
We didn't have to tear down any walls to move it in and when we need it we do not need to go outside our house to get into it.
