Been a customer for over 5 years at Realchems, and the person who referred me to the store knew them for 2 years before me. They have always delivered my order and been such a pleasure to communicate with, consistently with such high quality products and standards, paying very much attention to detail to assure not messing up an order or shipping a wrong product, only 1 time this happened out of hundreds and hundreds of orders, with a product similar to another ones name, but I was able to tell on the label and they apologized and reshipped my correct order immediately, which is another safety thing I love about RC, they have their stuff professionally packaged so you dont get wrong products in wrong labels. This company is awesome and has amazing employees that always act professional. I can highly recommend it to any research labs who's in need of their products. Thought to finally give them a review since I want others to know that this is a place you should not be afraid to have good business with.
