I've been using Rapidfinil for a couple of years now and they're fantastic. They deliver very quickly, usually takes around 5 business days in my experience. In the years I've been ordering from them, I've only had 1 issue with delivery and that was on USPS, not them. Their customer service is great, they respond to emails quickly. They have an excellent variety of products and everything I've ever ordered is legitimate, safe, and again--their shipping speed is a lifesaver. They deliver so much faster compared to sites I've used in the past, and they're the only vendor I've found who delivers USA domestic. They're the best vendor I've ever ordered from and the only one I use.
