Do be careful….. I bought a macom and didn’t like it so bought a high impact zip up front one from m&s. I was going to send the macom back but forgot. Nurse visit and I threw both of them in my handbag. Nurse couldn’t get m&s one to come anywhere near me as id swelled up so much so had to wear my macom. I got bigger n bigger and although the macom was stretchy it also got tight and painful and I wished id bought a bigger one.
