Everyone in the Southampton location was helpful. Had no issues with the unit.
I just don’t like that the price increased $50 after a few months. That’s a big increase for such a small unit

Anthony and Scott are absolutely the best sales people I have ever worked with regarding any industry sales folks quite frankly. I first met Anthony who was phenomenal, paid for my storage space and then came back for confirmation and Anthony was there again and actually remembered my name and I also met Scott who again was so great! I hope you all do something special for these guys and do whatever you need to keep them in your company!
