Will you please share all the data you’ve collected? That will help the rest here make a sound decision before purchasing.
I searched this discussion forum from last year and on the internet, and only found one offs for the 14PM. TBH, I didn’t search for prior years as that’s what I have currently.
If you find any technical articles on how the 15PM is built and why it’s just as durable despite the design change of the frame and removable back glass, please share those too. Looks like we both have a similar background in IT, so I’ll understand.
I saw the CR test, that was cool to see how they test them. However, I personally prefer real world tests. Like bumping a packed fanny pack into a grocery cart and the back glass breaking.
Glad you’re enjoying the 15PM!
