Excerpt: The TR Power Pack III does a great job at its intended purpose -- providing fast recycle time, maximum flash power and extended battery life. However, its problems (which lowered my review from 5 to 3) all stem from one thing: the connecting cord. First, the cord is short. I knew this from other reviews, but didn't realize how short it was.
Pros: Consistent Output, Fast Recycling, Powerful Output
Summary: Worked great and as advertised on my Pentax K10D, *istDl, LX & 645's. Compact, reasonable battery life and excellent output. Looked very promising until the first failure in week 2 when the internal flimsy plastic linkage that retracts the pin locking the flash to the camera hotshoe failed and the flash and camera body became one piece. A second failure occurred just after warranty expiry.
