I got a half check from PaH, but looking on their website the one I've got isn't on there. Were the ones that you had fail the ones with the snap fastener on? (Thats the only one they've got on their website atm). The one I've got I've had for at least 2 years now and never had any problems with it. It's an adjustable one with 2 sliders on it - it's actually really difficult to adjust the sizing on it.
