What if something breaks or fails on the photo booth?

Our company have multiple booths. If it is a simple error or breakdown, we can simple swap it out with one of our spares. Should something major go wrong, we would attempt to replace it within an hour.  This has never happened to us as we use the highest quality in the design and manufacture stage. We also do system tests when the booths take a break to insure there is no potential issues when they are send out.
