Hi there
I have contacted both of these companies, swiss and susan, and swiss dermyl customer service was pretty poor, they take days to reply to emails and about 3 weeks later i am still waiting for samples. Whereas Monu replied very quick and i had samples the next day, they also follow it up to make sure you have received everything you need, prices are very reasonable, I am just trialing between these and Moor spa, who again very good experience so far before making a decision!
