Best upgrade i have got for a cooler for any family outing!
on June 23, 2026
Posted by: MaryanneW
The Ninja FrostVault cooler has been an absolute game changer for our family boat trips! It keeps our drinks and lunch perfectly chilled, which makes the day so much more enjoyable. One of the best features is how easy it is for the kids to grab their lunch without us having to dig through a messy sea of drinks — everything is neatly organized and accessible. It’s durable, reliable, and keeps everything cold for hours. It’s made our outings so much more fun and stress-free. I highly recommend the Ninja FrostVault cooler to any family looking to upgrade their boating experience!

Doesn't work as stated.

I bought this cooler about 2 months ago and I hate it. It doesn't keep ice as stated. My igloo cooler works much better. It keeps ice for a couple of days. Ninja cooler doesn't keep ice for a day.

I never doubt a Ninja, or Shark product. My husband is always amazed on how great the coolers can keep everything cold for days(I have the bigger cooler too). All I say is of course it dose.
I would recommend this to a friend!

Love it!

Love it, but it does have a few flaws*
Love:
- It's a cooler. It's meant to keep things cold. 1000% it does and it does for an extensively (days) long period of time. I think it took ice to completely melt, 4 to 7 days.
- The FrostVault! This is pure genius. Keep things really really cold without them getting wet. My sandwiches, steaks and chicken, thank you.
- The seals, the water release valve, and overall craftsmanship, are top quality and very well thought out.
I took this camping (3 days/2 nights) two times as well as a track day and overnight stay. This guy has been through its paces. Overall, I love this but there are a few things that hold me back from giving it a 5 star rating.
Gripes -
- Probably the biggest gripe is the weight. This guy is not lite and doesn't get any liter when you add a 15 lb bag of ice and food/drinks into it. I had a little wagon I put this in and then wheeled it around (hmm). * Later on life Ninja listed to me and everyone and created these units with wheels. I'm going to expect this gripe would be gone with that unit.
-My second gripe which was a surprise to me, but it makes sense after seeing how well this works and honestly, I'm ok with the sacrifice, is the space. For how big this is, there isn't a ton of room for food/drinks (because it has a lot of insulation that is well thought out to keep things cold). Maybe they could have less insulation space for more food but then maybe my gripe would have been the cooler doesn't stay cool long enough? So this gripe is an ok tradeoff I suppose. Which leads me to my last gripe.
- The unit is bulky. I was a bit of a hassle trying to find a place I could put it in my 2025 Subaru Outback.
- Lastly, the price. It's come way down since I purchased mine but I think other coolers (that don't stay as cold as long) are cheaper.

Overall though, I LOVE this cooler. Its nice and sturdy and was used as a seat many times (without worrying about it caving in). If you can spend a little more on the FrostVault with wheels, I would highly recommend that route. I'm glad Ninja listed to everyone that raved how amazing this unit is but it just need wheels to be awesome!
I would recommend this to a friend!

This is one VERY COOL cooler
on March 3, 2025
Posted by: JohnnyD5254
Not only is it beautiful, but it is sturdy, rugged, and has marvelous capacity. I am becoming a total Shark/Ninja geek with all of the products I own. They're pricey but the value is well worth it.

Love this cooler.

I requested this for Christmas, absolutely wonderful present.
I am senior citizen that camps alone and I was having trouble draining my six day cooler, the location of the drain plug is perfect, I just lean it out the back of my van and drain.
The drawer works as stated and keeps food just right.
I am looking forward to warm weather to see if it holds up. If it doesn't I'll be back with another review.

Absolutely love it! It keeps ice for days and the drawer keeps food colder than some fridges, it is by far the best cooler I've come across. Definitely worth the price tag! Quality 💯
