Needed it fast.
Needed this specific product for a client task. As always the main criteria was getting the item quick as this was a urgent task.Delivery was quick and well packaged. The product worked well but as this product was a requirement by the customer I don't think it's fair to compare it to other products. It has remained flexible and provided a weatherproof seal on the component.
