Works great! Nice and bright, I use it everyday and makes life so much easier. I don't have any issues with the cap unlike others. I've been using it for over 6 months and the lid has still not been removed. I keep this tracker with all my other fiber tools and treat it like a valuable tool and don't let it roll around in my bag or toss it in some bin with other larger tools. I am very happy with this product and will buy another one if needed.
