Careful!!
I bought a bunch of Yardon "custom-colored" "Mag Darter-knockoffs" on ebay a couple of years ago from a guy in NJ. The wire inside is thinner than the Yo-Zuri's and after 2 or 3 fish they crack at the hook hangers, start to leak, and then sink like a rock with no action. They were clearly not sealed correctly.
When I complained the guy tried to say I did not know what I was doing & the Power Pro and Saltiga spinning reel I was using caused the problem.
Funny, no other plug I use does this...
Shame because the colors were very nice.
Not even worth a penny in my book. Now I'm stuck with 7 or 8 more that I use for casting & fishing practice for my son...
Sometimes "deals" are really too good to be true.
