Yes, I received the retrofit a couple months after getting the tank. Knocking on wood! Ha. Funny thing is that I really wanted the 750. Brs had several RS sales and the 750 was always out of stock. It was out of stock for over six months. I called brs and all they told me was that they had no clue when it would be in stock again. As it’s drop shipped from the manufacturer and not an item that anyone just keeps a hundred of in the warehouse, I called RS. They told me that there were plenty available and didn’t know why brs had them as out of stock. RS gave me three authorized dealers near me to order from. In hindsight I made this purchase at the end of the flawed run in 2019…brs probably did exactly what I would have done as a supplier…stop all sales of a product that appears to have a known defect. That’s my only gripe looking backward, that rs who knew at that point there was a problem, allowed orders to go through. The retrofit kit shipped two months later. At least hold orders until they could include the retrofit kit at that point the kits were in production. This was before I lurked on any forum. Also, disappointed that the lfs who most likely knew of the issue with that model didn’t say anything like you might want to get the next size down, wait for a minute, look at this other brand, whatever. It’s not like they had it in house and needed to get rid of stock on hand.
