I have used this pump several times on an old dragonfly drove I at auction on eBay that had a cracked and distorted area around the pump valve. It was the old blue straight shaft version. I trust this new pump, and it makes my old stove work like new. It is of good quality and like many reviews, I believe it will last a life time of wilderness and back country camping trips.
