We have used McCollister before, but we had not worked directly with them until now. We needed some help with the process of getting our old computer hard drives destroyed. The service was very professional, and they were able to help us determine what would be the best way to get rid of our old computers. They also helped us understand how much it would cost to destroy our old equipment properly. It's a little expensive, but worth it in the long run. We are satisfied with how easy the whole process went. I can't think of anything that I disliked. The only thing I dislike is how expensive this is. If you have a lot of old or outdated electronics, or hardware that needs to be destroyed, then this could be helpful. When we first started researching the services that would be available for our old computer equipment, we realized we didn't want to use a regular dumpster. There were too.
