To begin I was especially impressed with the order delivery cycle. Regular shipping practically overnight. I have not had an opportunity to try the stopper I purchased. I need to complete some shape changes to use this item in my maple syrup evaporator. I believe the item will work once it is "re-manufactured". I needed an item that could stand moderately high heat and could be used to open and close a port easily and quickly. I think this item will do the job.
