Dhgate.com - what products to avoid?

What do you avoid on Dhgate.com. Do you avoid namebrand electronics, clothing, jewelry,etc? Also what sellers do you avoid? What about Dhgates escrow service? Is there escrow service the same as escrow.com. Has Salehoo bought different items from Dhgate? Last, What sellers does anybody recommend?

These are things a few of us want to know? You email some sellers and they don't respond. This makes me mad....very mad. Somebody let us know and please any comments are welcomed.

I steer clear of just the ipods because almost all of them are replicas.

Everything else seems ok to me but the profits are small because thier shipping is usually high.
