I used Frogbox for my recent move in December 2015. It was my first time using them and I will definitely do so the next time I move. No more cardboard boxes for me after using Frogbox!
The service from Deb, who managed my order, was excellent. She responded via email quickly and provided all the information I needed. She reconfirmed closer to the move date as well. The delivery and pick up of the boxes was on time and no fuss. The price was exactly as quoted.
Frogbox is very convenient and environmentally friendly. The containers are very clean, easy to label, stackable, and keep your stuff damage free. Best of all, I wasn't stuck with tons of boxes to dispose of (or collect from various sources!), which is time consuming and not good for the environment.
