I ended up not needing the unit after all and cancelled my lease, however during this whole time I had an A1 customer service experience with Jack at the Sun Prairie location and online reps. Communications on my rental options, sales and types of units was very clear and useful. Getting set up was quick and easy. Will recommend and will look out for them if I ever needed extra storage.
