Thanks Mike Cash for letting me know about this. At first I didn't think it was worth because of the lack of power but for about $20 its not that bad.
You're very welcome.
For the ease and range of adjustments, the compact size, low price, flexibility, and Pentax dedicated compatibility they're just damned hard to beat. Definitely great for folks who are on a tight budget or who want to experiment with flash and not lay out big bucks up front before they know if that sort of shooting will appeal to them or not.
And at that price, one doesn't mind letting them lie about the place for extended periods between uses. Lay out big bucks for a flash unit you seldom use and the natural temptation is to sell it and apply the money toward something that gets used more often.
