ACEVER LED High Visibility Flashing Safety Armband Cycling Jogging Walking Reflective LED Armband Christmas and Party Tool(White)

Not worth £4.50 , not even £2.50, lasts only days , build quality is like a kids toy. You get what you pay for or maybe even less. No point buying this as it would only last days because of the exposed battery underneath a small elastic band. Even a drop of water or sweat could make it stop working. 2 CR2032 batteries power this thing (not AG13 Batteries as mentioned in description), so not much of problem if you wrap some tape on it to make it a little water resistant. Here in Ireland it is not suitable at all as it rains most days. If you are considering it for dogs, better get something that is at least water resistant and better yet, rechargeable, battery changing in these small things is a pain.
