This product is a good bit of fun.
It arrived from seller with a nice little note and a small plastic bear, which was a nice touch, though I admit the little gift went in the bin!
The light is not very bright, and it doesn't actually come with the bolts to attach it and it's not all that obvious what the best way to attach it to he wheel is! There are 2 slits for spokes and a hexagonal hole either side, which fits a bolt head. Problem is, the bolt head then goes all the way through, so you need to use a larger bolt, which lead me to wonder why it's a hexagonal hole...
On the other hand, for less than a fiver, I didn't expect a spectacular bicycle light!
