It was very helpful to have someone pick up my documents from home insteadof me having them shipped offsite or waiting until I could drive myself out there again! The cost is higher than other services we use but it's worth every penny if you're looking into shredding more then one document at once (we do 2-3 per hour).
When they came over with our shredded papers in boxes their presence felt like an extra layer between us & customers that were not necessary since this service will come by themselves each time anyway so no need / hassle/etc etc :) They did however offer some samples which gave confidence about what type(s) would be good enough quality without being too thin when cut apart later downthe line - otherwise i'm sure any client who has used these before can confirm how important thicknesses matter here ;).
