Hi mate,
Did you ever tried or tested any of this aliexpress M7 capsules?
If you tried what did you concluded?
I can understand what people said around here about it being a lottery, it is with a lot of stuff I bought over the years from China/Aliexpress, it’s made for a budget and quality control it’s almost non existent, so it’s a hit or miss sometimes.
Of course I don’t expect the same lottery with known Chinese capsule brands, like 3UAudio, 797 and Takstar, but with cheap generic unbranded Chinese components sometimes you never know what you’re gonna get because the production is not consistent
