Fantastic product. Works great with the Vectra thread and needs little to no explanation for use.
The bullet should come with extra elastic though, as one of mine broke about halfway through it's use. Other than that, it is an amazing product, and there are ways to use it even after the elastic breaks, as long as there is some pressure on the thread it won't unspool.
