Product Customer Reviews

Excellent for running - wish I’d found this before. This would be great for travelling as well as it can be worn under you t shirt with no visibility.
the clip keeps slipping off making the belt fall to the ground with the phone inside
Hello David,
Thank you for taking the time to write a review, and our apologies that you were not fully satisfied with our quality on this occasion.
This is absolutely not what you want from a product designed to hold valuables. As we have had virtually no other reported faults of this nature for the product we would of course swap it over if you could possibly bring it back to your nearest store to resolve.
We pass all quality related feedback through to our product design teams so that they can review, comment or check as necessary. Our Running Belts are extremely popular so every effort will be directed to ensuring there is no compromise to the overall quality on larger scale.
Once again our apologies for this inconvenience but thank you for bringing it to our attention.
Best Regards
Mark
Lightweight, soft and stretchy material. Easily fits my Samsung A series phone and cover. Love the hidden key pocket.
Fits my Samsung phone and cover. I like the key pocket also. Soft and easy to wear.
I always use it
Good product. Key holder a bit too small and hard to access
no comment
This product is great in theory but the elastic comes lose while running with an iPhone inside. It would probably be okay with keys only.
it does what it should. Occassionaly needs to be re-adjusted while running
I used to hold valuables during a triathlon the straps are good quality
great fit and great value
Perfect! Good product
There’s a tiny pocket inside for key which I think is a brilliant design! Love it!
Neat and comfortable to wear, easily fits phone and keys.Great for
This is great for your phone and keys. It leaves your hands free. I use regularly, every time I go for a walk.
