Needed a way to clean up the counter when we had multiple devices charging. When looking for a charging dock with a couple phone slots plus something for a tablet I just had a hard time finding anything that worked for our needs. The design of this is simple. Just 4 slots between 5 walls so you can stack phones or tablets while charging. Magnets not needed underneath but I like it to not lift up when taking tablets out. Also works for stacking mail or other items like that.
