I haven't tried any KastKing rods so far. Only their braided lines.
What are you planning on catching with it?

Me neither !!

I wonder why it has 2 top sections...

I'm assuming that the two tips are for throwing two different ranges of weight.

Mine rod (an Okuma) only came with one -- I now have a second tip (salvaged from another rod) that loads up better and gets me increased distance with lighter weight.

Never bought a rod but their megatron reels are fantastic

I started buying kastking baitcasters for myself and spincasters for my wife about 3 years ago. Found they compare favorably to shimano and abu in the 1000-3000 range at less than half the cost. Use them for inshore and near shore and am impressed with their durability. Have not tried the rods yet as I hesitate to have one shipped by Amazon . I’d be interested to know how they hold up in the medium heavy size

I had bad experience with the Megatron spinner, drag knob went bad twice for the same reel. But I understand sometimes the odd product will have its defect. In all fairness to Kastking, they replace/fix your reels once it's under the warranty period, which is good. I even got one of my reels replaced free of cost. Still have that one a few years later.
