“We've been using Vitals for our store at Bigksport and it replaced at least 6 separate apps. The product reviews, upsells, shipping estimates, sticky add to cart and visitor replays all work seamlessly together. The fact that it doesn't slow down your store while doing all of this is the biggest win.”
