- Tsbsb05 shock relay - Had no idea of Miro supply and after exhaustive search on internet came up with Miro Supply as having the item I needed and the price was well below others that I had found for the same item. It arrived in a good timely manner and was as a new item that was described and worked fine and got my smoker back up and running again. Will look at this site for future items that I may need.
