I have really bad arthritis in my knees and I hold myself together with KT Tape. Seriously, I couldn't work without it. It works better than any other brace I've tried.If you're used to working with KT Tape, this will be a great buy for you. The precut stuff is nice, but the cost really adds up. Sure, you have to take a little more time cutting everything to size, but for this price, it's worth it.The roll has a faint line where every strip would be cut on a precut roll, which makes sizing the strips in a uniform size MUCH easier than other rolls I've used. The ultra strength adhesive is not irritating to my skin but lasts at least 2 days. I have pretty sensitive skin, so I really appreciate this.For professional or personal use, this is the best deal I've found for the price
