I was hesitant to try a new grommet assortment but this product surpassed my expectations. It includes a wide variety of grommets that fit perfectly with my electrical conductor work .After I put it to the test, the grommets held up well and prevented any wire damage. The product is also well-priced for the amount of grommets you receive. The only con is that the packaging could be improved to make it easier to quickly find the right size grommet. Overall, a great find for anyone in the industrial and scientific hardware industry..
