ITTSB Blog this engaged with BRYMEN products reviews since 2011.
BM257 and BM869 these was from the first arrivals.
About BM257, I have use it allot, always gently, test leads wires they were discolored from exposure to sun light, but they survived for 14 years, this month both of test lead probes their rubber cover, this started melting down. :P
Both test leads probes, they have now become as sticky and unusable. :P
While BM257, RED rubber holster, this does not show aging issues up to date.
About BM869 I have use it but not allot, even so, BM869 test leads, one of them demonstrated issues at making good electrical contact.
At banana plug connection to wire, BRYMEN this using crimped method, this connection loosens, and this test leads pair it become useless.
The only fix, this is both 90 degree banana plugs to be replaced with new.

Over the years I did read and other users complains, about BRYMEN Tests leads.
In some occasions especially of nervous users, it might sound as possible to kill one good pair of test leads, by pooling the wires of test leads, due an accident or due misuse.
In my case, I always was super careful, and therefore BRYMEN manufacturing this using crimped method this is to blame.
If you live within European Union, and you seek replacements for damaged BRYMEN test leads?
I am thinking of HIOKI test leads as a much safer bet.

Hioki L4930 Connection Cable Set, this seems as reasonable priced retail with VAT. :)

This cable set, it is the nearest equivalent, for Keysight or FLUKE modular test leads.
Never tested or owned this specific Hioki L4930, but its now added at my wish list.
Hioki does not inform of wires supported current capacity.
But it should support 10A continues.

Basic test leads = HIOKI L9207-10
But the assembly this is made in China.
However any product this be made according to HIOKI specifications, this expected to be of elevated quality. ;)
