I like the idea of this. For someone like me, I like to keep it simple. The product inside the tube is great for the few things I've used it for. It had a strong hold and haven't had issues of things falling back apart. But it can be messy. I have tried adjusting the slide and it either gives nothing or too much. It doesn't adjust well enough to really control what comes out of the tube. It would also be nice if they had interchangeable tips. It's basically 1 size and I feel it's rather thick. Again, it's the lack of control that bothers me with the design. It's not the product itself, which works great
