I have both. The clones are awesome and I recommend them to everyone.
The original is fucking awesome! But given the price I can't really recommend it if that makes sens. I love my genuine and will never part with it though.
Honestly you'll never be unhappy with a decent clone. Ivogo springs to mind.
I bought the original as a tribute if you will. A way of saying thanks to the creators for bringing that post style to the market. (at least I think it was them who were the first, certainly the ones who are recognised as the ones. 'Velocity style posts' are on loads of rdas/tanks now and how they are are even marketed)
