I had two plastic top, single handle corny kegs. One was red the other was green. They both are old and not new. They are the single handle style. I had trouble with one of them leaking past the relief valve and had to change it to a different lid. I tried swapping relief valves, but the leak was in the lid. I think the poppet seat just wore out. They were fine for beer.
