If you have used other drip tips you will see immediately why super t's are more pricey. It is because they actually work, they are a true drip tip. With other tips I notice that I end up taking the tip off to drip but with these ones there is virtually no stuck liquid, at least for me. Thay are also the best quality you can get. I believe there is a lifetime warranty on the stainless ones but check the site to make sure.
