While I wanted this product to work, unfortunately it's more trouble than it's worth. While some nozzles fit better than others, changing nozzles was a hassle and a waste of time and tape used to hold the product in place. I'm better at fingerwork than with this product. Also, some of the nozzles were too small to fit properly on the sealing tube and moved when sealing. Additionally, the attachments have added extra length, making it difficult to work in tight spaces. I would recommend continuing to work with your fingers, practice makes perfect.
