If there was an award for the absolute customer service, they would win. I'd highly recommend that you DO NOT do business with this company. They have friendly people (call center) who are more than happy to lie about what they have available and take your credit card info. I reserved a unit in Dover NH to store a car. The unit needed had to be at least 25 feet deep and with a 9 foot door. He found me a 10x30 with a 9 foot door for $230 per month. Took my info and for some reason, pressured me to get there the next day. I said Maybe, but I've very busy. He said, no problem, get there when I can. Well, my reservation that he set for 24 hours (without my knowledge) expired. When I called to extend and finalize the agreement, they said that unit is no longer available, but lucky for me, they have another one at $317 per month.... and "sorry". Talk about bait and switch! I went to the actual facility. They not only confirmed the same thing, but told me that their Dover location doesn't have 9' doors. So it's all for nothing. This is what happens to local business when they sell out to corporate conglomerates. Business becomes about maximizing profits. Things like, taking care of people, service, integrity, honor, and doing the right thing are gone forever. I'm a local business owner, and these things mean everything to me. It's sad really. I'll never rent from this company. ... Read more

At the beginning, I loved this place! I had used it for things while I was deployed two other times and had no issues. People here use to be excellent and convenient. Well I got overseas this past year / may 2025- may 2026, and this company got bought. The new owners started with pushing my rent up over a hundred dollars a month and when I complained, they basically told me to have someone move my stuff from one storage unit to another… I am overseas and barely had time to complete the lease nevermind try coordinating friends or family to drive hours to move my stuff for me so that I could continue at my first contracted rate.. they said sucks and I had to pay over 200 a month for a storage unit when it originally was right over 100… I got back from overseas and complained and they did not care or try to make things right at all with me.. “valuable customer”… I will never be using this storage place again… I had no issues overlooking the horrible gate issues but customer service is everything… if your a service member, do not use this place.. they are here just to make money… your a dollar amount and not a person to this company. ...
