Loupes for diy electrolysis magnification

Hello, I am considering purchasing 3.5x TTL loupes from China and was curious about others’ experiences with cheap Chinese loupes and how they compare to alternative magnification methods such as magnifying lamps. Also, what working distance and lighting do you guys use?

I would buy something that come with a set of magnifying lenses that will offer different working distances you can figure out what will work for you.
