The adhesive on the back on the stat lock made me break out in a horrible itchy and stinging rash. These are a great alternative for a stat lock. I have only tried these on my chest, to keep my tunneled catheter (central line) from pulling out. They do a great job and don’t irritate my skin. I have EDS & Co., with a suspected diagnosis of MCAS, so these have been a miracle. Without them, my catheter pulled out and was painful and bled a lot.See full review
