This post is for research purposes only. My wife and I have gone through them on two occasions now, and both times have been amazing. I just wanted to review on product accuracy, customer service, and shipping. You get what you order. Plain and simple. Second, the customer service is phenomenal. They were able to fix a mistake I made on an order I placed at 7pm at night. Jason was very friendly and we will be definitely be using these products again for our research. Also, shipping for our first order was super fast. Within 2 days of ordering, we received our package.
