I just received my KO Battle Hooks for my Striker Prime and they are amazing. I paid $18 shipped from eBay seller gigaproshop. I ordered them on April 11th and they were delivered on April 23rd. That's pretty quick, especially when the delivery estimate was May 10th-23rd. I happen to have a set of the real Striker Prime Add-On Swords for comparison. I will say that the plastic on the hilts of the KO hooks is easily as good as the real thing. The plastic on the hooks themselves is more delicate, but I think that is more due to the greater transparency and the fact that the designer was emulating the bonus hooks that were available with the limited version of the DMK01 Optimus Prime Dual Model Kit by Takara. The orange plastic of the KO and the Takara swords are not even close to matching, but that is ok. I like the color of the KOs quite a bit better and they seem to match the coloring of Striker Prime better as well. The detail on the KOs isn't as intricate as the real deal, but it is surprisingly good. The fit of the handles is nice and snug in Prime's hand. The scale of the hooks works great despite the fact that the hooks were originally designed for the model kit figure rather than Leader Prime. Personally, I very much prefer the look of the KO hooks to the official Takara add-on swords. I never have Prime displayed with the swords in-hand, but I will have him with the hooks. Overall, I am very glad I picked these up. The quality seems really good even if the hooks themselves seem a little delicate. When you compare the prices of these KO hooks to the prices of the offical Takara swords, it is a no-brainer. These hooks are much better for the price and in my opinion they look really good with Striker Prime and look tons better than the hooks from Battle Hooks Prime and even better than the swords from Takara.
