BRYMEN clamp meter RED rubber material over rotating functions switch FAIL

[Kiriakos GR]

At 2015 I did accepted from BRYMEN, one BM079 for a product review.

Today = 10 years later, it RED rubber material over rotating functions switch ( functions selector ), this started peel off.

Peel off = RED rubber this starts breaking in to very small flakes.

I consider this as first stage of rubber surface degradation.
The rubber surface even after a period of 10 years, this is remain as soft, but it seems now getting softer than of what it was as new. 

BRYMEN uses identical RED rubber material, at their entire products range. 
Over the years I was cleaning this part functions selector very gently with soap water.

FLUKE clamp meter they come with a plastic cup as functions selector, this is impossible to degrade.

I am now convinced, BRYMEN never did enough Quality Control tests, about the longevity over time, of their rubberized materials.
Naturally today I feel as very displeased.     

Note: There is no replacement part of this functions selector.
