I love the zip binder tool. Works perfectly. The binding tabs stay on but easy to remove and reuse. Martelli has quality products. I like making do and being creative when it's something I won't be using a lot of but if it is a product I know will be used many times I will buy the item made for the job. This thread holder is pleasing to look and has easy adjustable heights, no rigging to manipulate to make it work. After evaluating the pros and value, it's worth the price to me.
