I have had so many complements from strangers about this breastplate, on how well they could see me with it flashing away! The lights are VERY bright! It's a definite 'must' item when hacking in the dimpsy/dark evenings. I'm very pleased with it, as with the amount of people (walkers/drivers/motorbikers) who have said about its excellent visibility, really makes it a worthwhile purchase. It's an expensive bit of kit, but worth it.
2 negatives; after only a few uses the pink covering has already started to crack. Hopefully this doesn't lead to letting water in & ruining the lights! I keep it stored hanging flat, so it's not as if I've had it crumpled up in a cupboard, so I'm a bit annoyed it's cracked so easily. And the other negative is that the on/off button for the bottom piece (that attaches to the girth) is right down between the horses legs, so you have to turn it on before you ride. I think it would be better if it could be moved higher up so you could reach it whilst on board so you could turn it on if you needed to if it was getting dimpsy.
