Electronics marked as ESD sensitive can be damaged pretty easily
After all why would a manufacturer spend thousands per year protecting their products from it?
I usually take a lot of precautions when dealing with electronics, it might not
explode infront of you but it can cause latent damage that may result in failure later on
I use a strap and also a modified cable to plug pc into wall (only earth connected - not live or neutral) when I am working inside it
