I thought that the nano helmets would fit the original key chain buddys that I've had for a few years, I bought the helmets to replace the default ones on the originals, thinking it would save me buying a whole new key chains. there's no hole to be able to do this so now I'm left with 3 nano helmets that I'm not going to use. This should be made clearer on the website.
The detail is spot on though.
There's no link anywhere to contact someone as I'm missing an item from my order.
