I buy from TMR when I see a newer item I want. Why ? They offer a trial period
so returns are allowed. That is a value. Some idiots buy gear and unload it before
it is even burned in. Consequently they never heard what they bought at its best.
So if you buy a brand that allows warranties to pass to the next owner-such as Pass Labs does- you can do very well.
That said TMR does not test everything. Last item I bought was never checked.
They did give me a $100 credit toward the next purchase when I brought it
to their attention.
Do the leg work with a serial number and call the maker yourself.
