We understand that some customers are skeptical of our product and how it works. If you are one of those customers, please take a look at this video. This video follows the Pratt Family as they try out Harvest Guard Reusable Canning Lids for the first time. Mr. Pratt does make a couple slight errors and shows us quickly that its not the end of the world and how he can remedy those errors for next time. He not only gives a fantastic tutorial of Harvest Guard Reusable Canning Lids, but he gives a review of them, as well, stating that he likes them and will be using them again in the future!
