Query: Topeak JoeBlow Sport Bike Pump

I received this as a gift, and felt it worked okay for my road bike initially. However, from the beginning had a little trouble make proper connection to tire stem. Unfortunately, connection broke within 8-9 months of use. I borrowed another make pump from a friend, which (even though several years old)connected more easily. When it worked initially, no problem with pump mechanism, but connector is just not durable. Reading other lower reviews on this model appear to hold up my own experience.
