Well I was wearing the PA5000 with very good success until a few days ago. While working a large heavy metal door shut on a heavy metal box I was carrying. The problem was the box was at my crotch level being carried and hit the cage of the PA5000. This snapped the top bar of the cage and also split it open. So when home and explaining to the wife she was not happy that the plastic split. She is worried about the plastic splitting and causing harm to me. She pointed out the birdlocked and the fact it is soft. I agreed and wanted to know if anyone has had good luck with the new 2010 models? I plan to possibly order the PA version in the new clear silicon look. The first time I tried the Birdlocked I didn't have any luck mainly because I believe I didn't have the right size. A mini was too small and being pink I couldn't see what was going on inside. I would love to hear from anyone that wears the device longer than a few days. The PA version will insure the security and no slipping out. THanks!
