I have been burnt before, but could not resist.
They have not yet arrived, but it usually takes a long long time to get here!
We were talking about these cheapo handles on another thread here and I summed it up like this: A $10 chinese handle is like a lottery ticket...might be a winner...and it might not! 
Maybe I did not make the connection or did not see. Ill let you know what I recieve, maybe suitable for a sinker

I suddenly remembered that I promised some more info.....LOL
I Eventually received the two handle knobs, took 2 months all the way from China for about $5-00. Looks OK, a little bit light for my liking, but it is what I ordered. I fitted one to a Penn Fathom 25N handle, went and made about 20 casts and retrieves with it and packed it away.
I fitted it about 3 mm inside from where the original knob was and it does not "feel" quite right but I probably have to get used to it. I don't like the reel so don't know when I'll use it properly so I can provide a durability report.
I can't figure out how the Chinese can mail stuff overseas so cheaply. They must have some sort of government subsidy or incentive program.

Yes, they shipped it to Cape Town via Sweden?? must have some sort of scheme! I also got a $5-00 discount from Alibaba which made it ridiculously cheap, 2 handle knobs, including bearings, for $5-00
