Interestingly, for many devices' initial failure rates might be higher as some devices might have factory defects or weak areas. This is often called "infant mortality" in engineering circles. So you might have a 2-5% failure rate the first year before it settles back to lower rates in year two and onward.
The more complex the device and the more critical components it has, the more pronounced infant mortality is. IPPs are pretty simple, but every primary component (reservoir, pump, cylinders, tubing) is critical to device operation.
Thank you for this, ElbowRoom. Infant Mortality Rate is a fascinating concept in reliability engineering. Very insightful. As I was looking this up after your post, I also found this "bath tub" curve and thought I'll attach it here.
This is literally the shape of my dick when I wear a jock strap. it appears fake like a 1/2 moon because the tubing pushes it out, and the jock is pulling it down, but it buldges out in the middle of the curve. It looks like I am always fighting an erection. NOT GOOD FOR EXPANDING YOUR BUSINESS if people think you are always sexually aroused!
