    Read some helpful reviews of Prime Storage, shared by real renters with genuine experiences and honest opinions.

    What an absolute joke this place is! I've had a unit there for over 10 years and all of a sudden somebody enables auto pay on my account. They drain my account taking a payment this morning leaving me and my family with $20 in my account until the next Friday. I get told that they'll discontinue the auto pay but I have to talk to the branch manager to get any money back. Then get told they'll have her call me back. This is happened twice now that I've been told she'll call me back and nothing! Don't waste your time with this place is a joke!!!!!!! ... Read more

    Carlos was very helpful. I signed up for a unit over the phone with someone else, but when I came to the units he worked with me to get me into a unit that was the same size but easier for me to access. ... Read more

    Our overall experience was meh. When I signed up, I signed up for a lower rate. Within 2 months my rate jumped. So it was hard that I signed up for one rate and within a couple months, my monthly rate jumped up quite a bit. I also uploaded my private insurance which I even confirmed with my private insurance that they covered storage unit rental insurance. However, my insurance coverage was denied by prime and I was forced to use their insurance. Also, unit was infested with mice and we found feces all over our unit and personal belongings. I know they have mice traps on sight. But overall at the end of the day it is what it is. The real downside is the “hours” instead of being able to access my unit 24/7, we were restricted and had to come within a set time(which made early access before 6am not possible to access my gear and after 10pm I would have to wait for the next day). Super inconvenient but I just dealt with it. Just know that your rate will go up shortly after you move your stuff in and the hours are not 24/7. If you’re okay with that, then you’ll have no problems. ***Edit for prime feedback, why would I contact the onsite manager? I already moved out and don’t care to do more than this. Just want to make sure others are aware of things before they move their belongings into this storage facility*** ... Read more

    Cada 2 meses te van subiendo el pago , a lo menos 10 a 15 dolares. Entre pagando 200 y luego de 6 meses ya termine pagando casi 270 dolares. Atentos Be careful! Every two months, they increase your payment by at least $10 to $15. I started paying $200, and after only 6 months, I'm already paying almost $270. Watch out!" ... Read more

    The reason that I got the storage was because the 24-hour access due to my work and I called and left a message last night letting them know that I couldn't get in didn't get no call back tried to get in again tonight I still can't get in even though I paid the extra for it definitely not a good way to start off ...

    The gentleman that helped us were very nice and friendly and the cost to store our vehicle while we were on our vacation was very reasonable, it was worth it to me knowing our car was in safe hands so that I may enjoy my vacation without any worry. Thank you fellas of Prime storage! ... Read more
    Jamie B. - 21 June 2025
    Signed up February 4th. For a 10x10 the rate was $52 dollars a month, add $17 for their “prime protection plan”. And there was no introductory discount, just a small web rate discount. Now rent in the same unit has jumped to 109 and still add 17$ for their protection plan. Originally paying 69 total now it’s 126, that’s a 82% increase, some would even say exorbitant, especially where they are not offering anything more, same hours same pestering phone calls. Will be looking elsewhere for my future storage needs ... Read more

    This property changed ownership roughly a year ago, and I was hoping the new owners would invest in the property. The property is in desperate need of repairs. I have three units and I’m looking for a better option. One of my units leaks every time it rains or snows. I’ve been asking for over two years for a repair. One of my units has a bad low spot in front of the door, so when it rains, it either has a lake in front of the door or is bad muddy. I’ve been asking for over two years to address. In my third unit, I can’t raise the door half the time because the track is messed up. It’s been that way from day one! I’ve been waiting over two months for a repair. When you request repairs, it takes months before someone comes out and looks at the item. So far, I haven’t seen anything actually get repaired. The other thing I will point out is that there are some sketchy tenants occupying a few of the units, so I wouldn’t recommend going in alone or unarmed, especially late in the evening when the lighting is low. Sometimes when the gates break, the gate might stay in the open position for weeks at a time, waiting for repairs. I will say the onsite manager Carlos is a great guy and he tries his best to address your concerns but I believe the ownership doesn’t support him and the owners needs to either make a site visit and invest some money in the infrastructure of the property or sale it off to someone who is willing to make repairs. Don’t get me started on the rodent problem! If you have options, I highly recommend you seek another location. I chose this property based on location, but I’m looking to relocate all three units, even though it will be inconvenient. ... Read more

    Carlos and staff have been professional, freindly, helpful, accommodating and prices are sensible. If Prime stays with this formula and staff, I will look forward to doing bussines in the future and will recommend them to whoever has storage needs. Wayne Millhouse ... Read more

    Be aware!!!!!! Your stuff is not safe in this stoage. I had a jeep that I was storing in the outdoor unit, and a disgruntled employee stole it. It took the cops 2 months to find. Prime storage was no help at all and was unwilling to follow the warrant for the security footage. (The salt lake unified police department does not recommend doing business with them!!!!!!) ...

    DO NOT PUT YOUR THINGS HERE. This location is subject to gang activity and thieves. The staff have taken no preventive measures and will just pay you your insurance payment. NO CAMERAS. NO STAFF AFTER 6. FREQUENT BURGLARIES. ... Read more

    I worked with Carlos and Deborah to move from the West Valley City location to Magna. They were both very helpful with the move. Prices are much better at the Magna location. All units are drive up which makes it so easy to move in and out. I’m giving a 5 star ranting for Carlos. The only complaint I would have is that Prime Storage raises their prices on you every few months. They also do not pro-rate your rent if you’re moving out in the middle of the month or even the first week. You have to pay full price for the whole month. This would bring my rating down a bit. Besides that, Prime Storage has been a good company to work with. They have multiple locations. I would recommend them. ... Read more
