Ok product when they work, poor internal contacts mean the always on switch sometimes struggles to connect and I have to tap and flick the product to make it work. When they do work the light is bright and clear I just wish they eerie better made. I bought these for light painting with my camera but are a little too unreliable. They are almost ok to have in a tool box or hanging from your keys but couldn't be depended on for an emergency. £2.00 would have been a fairer price, next time I may spend a little more on a better product.
That said the seller was great with extremely fast dispatch and faster than expected delivery.
