Just picked up my BM786 and noticed that there are 2 cracks on the plastic case portion about 1/6 down from the top of the clear screen, which is starting to encrouch onto the clear screen itself on the left side. This meter has been pretty much babied, never dropped, and if it wasn't for my old eyes, I probably would have noticed these craks earlier. However, the crack starting to form on the clear screen itself are definetely new, as the crack causes the light going through it to have a prismatic effect and is very noticeable, even with poor eyesight, and that was not there last week when I last picked up the meter. Looks like plastic is failing because of a stress or a mounting point for a internal screw? Plastic getting old? The meter is about to be 3 years old as of purchase next month.
