Hmmm, I dunno what to say, except that mine is definitely an original RG Racing product, as I went to them directly and bought it.
The indicators on mine are different, but that's because I'm going all out for ultra bright LEDs and those are Oxford's Nano LED indicators. You wouldn't believe how something so small can be so bright...
here's a pic for a size comparison
Without having actually fitted it yet, I still find it real easy to recommend this tail tidy. Alot of my friends have recommended them to me and you can just tell by looking at or holding their stuff. You should see their crash protectors up close, makes those intuitive sliders look like toothpicks.
It's quality. Even the packaging is the nuts.
If you're not sure about the product on ebay, you could try shopping from them directly
