The reason you don't see all the fakes listed under the same name is that these ripoff poles (and I PROMISE you that's what you're looking at) are constantly having to change their names because they're constantly being chased by lawyers! They keep switching the way they list the poles so they can keep selling their CRAP. While it may look the same in pictures, I guarantee you the upper dome will probably be plastic, which WILL crack completely open when you tighten the pole.
If you look at all the reputable professional poles, x-pole, lil mynx, platinum stages, even hardcore poles, you will notice that they all fall into a very similar price range. That's because the materials involved are NOT CHEAP and machining all the pieces is a highly labor-intensive process. If they were not perfectly machined, you will wind up having serious problems with putting it together. Ask yourself, what must they have done to this pole that they can manufacture it for $200 less than a quality piece of equipment? There's no good answer.
PLEASE save your money for the real thing. You are probably the 25th person I have seen looking at the fakes, and in literally every single instance you wind up with a broken ripoff, and just having to go back around and get a real x-pole anyway, then you spent $500! Just save your pennies and order an x-pole from veena on this website. She doesn't even charge for shipping, so you'll get a wayy better deal than you could on ebay, where the shipping will be $40 flat rate to the US. If you save your money for an x-pole from veena, you will have a piece of equipment that I have seen engineers absolutely marvel at, and it will potentially be with you for the rest of your life. Don't underestimate what you're paying for with an official x-pole from veena. I myself was skeptical about whether x-pole was worth the money, but it is a rock-solid pole, and the safety and the peace of mind that come with it are literally priceless. If you don't trust your pole, you won't give your all when you're learning moves. And you deserve the fun of throwing yourself all over your dance partner! Good luck!
