Reviewers most often praise ProLon's product quality and the ease of following the 5-day kits, frequently noting clear day-labeled packaging and positive results. Customer service and delivery operations receive many positive mentions, but a subset of reviewers report significant billing, checkout or subscription problems. Price sensitivity appears regularly: reviewers recommend watching for discounts or promotions because several experienced unexpected charges or price increases. Prospective buyers should confirm subscription and billing details before ordering and contact support promptly if charges or shipments differ from expectations.
