This is my third Blackberry holster but not an indication of poor quality as much as my constant travel.  I tend to catch the holster getting in and out of cramped airplanes seats and rental cars.  The holster itself is well made, it is the swivel clip on the back that ends up breaking.  I am not sure how you could make more durable without risking harm to yourself if it did not let go when snagged.  Given the low price (compared to verizon store) I can tolerate having to replace every 10-12 months.
