I can't speak as to "how long it lasts", but it shoots real good.  My nephew has had one for 2 years and he likes it.  I have shot it some and it shoots as good as any 12 pump that I have shot.  It will take any chokes that are made for the Mossberg/Invector choke threads...not the Invector Plus, but the regular Invector chokes.  For $150 for a new one, its a pretty good value.  Actually been thinking about picking up a Pardner Protector, myself.  With the addition of iron sights it would make a great slug gun, too.
