I'm a regular customer Realchems since 4 years, and have to say I couldn't be more satisfied with their services. Everything was delivered on time, all the products were of a constant, excellent quality. Only during the early COVID-19 pandemics the courrier took sometimes 2-3 days more to arrive, but that wasn't their fault, and it didn't last too long. And last point : their staff is always reactive and absolutely friendly ! Their "newsletter" is much more than advertising, like what we are used to get, it's always a pleasure to read, it's cool and full of informations. They deserve 6 stars ;-)
