I took mine apart mid-show to figure out how it's doing it's thing. Brilliantly applied tech, but I couldn't help but think of the e-waste from those fans who don't cherish something like this enough to keep as a memento.
Edit: seeing others commenting on sustainability and pointing towards their website. Fair enough. Good experience had and it's not the worst.
Member of my team moved recently to 4x9.375 instead of 5x7.5. My company wouldn't allow an hours reduction at the same or similar salary, so he took the offered option above. He takes Wednesday off and seems to enjoy it. I'm considering the same now, too.
When I was younger (say, 7 or 8 years old), I considered myself a good swimmer and as part of my swimming lessons we were told to do length-ways with the aid of a swimming board [0] at arms' length.
Approaching the 3/4 mark of the length, I felt it slipping out of my hands and in my panic, I went down. I woke up after being resuscitated after a lifeguard noticed I was in trouble under the water. He had jumped from the top step of his high chair straight in apparently and literally threw me out of the water to a waiting colleague.
Not sure if I'd trust my own children with that type of flotation aid again, but as you said, it encouraged me to swim outside of my comfort zone and I panicked so perhaps more control is needed of when and where it is used.
On the introduction page of this course it states, "This course is intended for folks who have a strong programming background, but who are new to finance and investing."
