Review: Good for occasional use - Great product - easy to store and use. Good if you have limited space for a roof top box and only use occasionally. Just bear in mind that unlike a roof top box, you cannot leave this street-parked.
Review: Would Recommend ! - Amazing Quality, Fits perfectly on the car! No Leaking! Only noise is from the anti slip mat! But it's very quiet if you aren't listening for it! We use it all the time travelling over ferry's and 12 hour drives! I would recommend buying a different lock if you want to feel a little bit more safe with your belongings.

Amazing Quality, Fits perfectly on the car! No Leaking! Only noise is from the anti slip mat! But it's very quiet if you aren't listening for it!

### ⭐⭐⭐⭐⭐ Must buy for camping!
*by A***R on 13 August 2025*

Brilliant roof bag, cannot recommend enough! We use this for camping and have used twice so far and it has been brilliant! Carries a lot and safe and secure. Comes with an anti slip mat too. We have a Golf R which has glued on door seals so we couldn’t hook the straps under the seals, so we had to improvise and purchased extra straps so they go all the way through the car. Works great. I would encourage anyone to buy this :)
