Quick question!

Hi, I needed voltage regulators positive and negative 15v I think for my active filter ( high pass , low pass ) to power the op-amps.
This is all I could find at the moment in stock, are they fake? , china versions, Good enough to use them ? or should I trow them in the bin.

Also, how about just transformer - bridge rectifier - a couple of capacitors = dc -+ 12 - 15v ?. or you recommend Voltage regulators?.
