I was shooting my client's wedding for several days straight during their rehearsal weekend with about 15 people in front of me all day long as well as other events prior to this particular event which could have easily been stressful without using shootproof.
However once we started taking our photos there were no issues at all! The whole experience from start-to-finish felt so smooth that it made everything run much more smoothly than if i had just gotten off camera myself or used another service like Fotobabble who are very good but not always available when you need them most (which is often!). We ended up getting over 1000+ shots throughout both photo sessions alone because they didn't miss any opportunity while helping us out whenever needed along the way too unlike some services where they only get paid after your done editing/sending files etc. It really helped alleviate stress especially since.
