Well I know a lot of different people think differently about KO's.
Personally I have really grown to love them.
I live in China so I am constantly surrounded by them.
When I started to collect when I moved here, I was just getting G1 Reissues, and then I started to get some cheap Chinese brand KOs like the combiners and Shockwave. For the price they are here its totally worth it even if they are much lower quality.
But sometimes a cheap KO will really surprise you, sometimes (rarely, but sometimes) they are actually better then the original legit ones. SOme examples of this would be:
- Meantime KO that actually tells time unlike the real one

- Megatron Classics KO with lights and sound, when the real one has neither
- PAIRs of NIKE SPORT LABEL, right and left shoes
ALso oversized and mini KOs are really cool too, overall I love all KOs now and they are a big part of my collection, I just need more cabinets to display them all
I will always add pics of KOs here. I will start this week with the ones I currently have, a lot of my photos are of in package, but I have almost all of them opened. I just take in package pics for my sales thread/future store.
I will start with animated KO's since animated is probably the most popular now, .. Since the legit aniamted toys are readily available and not tooo expensive the KOs wont be very popular outside of China I still think they are awesome and I make sure I pick up everyone I see (I really like the animated toys).
Ok here goes,
some of my Haul pics from weekend shopping
ANIMATED KO's
This is the newest set I picked up, grabbed them last weekend. They are the exact same size as the regular deluxe class figures... pretty good for a Chinese brand KO.
I'll start with a comparison shot of the real prowl vs the KO

even the throwing stars open up - nice job
Voyager Class OP KOs compared to original - one with white is the first release, kind of loose, one with grey is second release - its pretty good
