best miracast cheap dongle ??

Hi guys,
I'm looking for an alternative to chromecast to mirror my s6's screen to my tv without buffering. What would be the best miracast dongle ? Ezcast, anycast , wecast , easycast ,... ?

Any way to use my allshare cast dongle with note 5?

I have tried several different methods to hook my phone up to my allshare cast.

Try as I might I can only seem to get a "connecting... failed to connect... connecting... failed..." loop.

I tried contacting Samsung Galaxy support but I'm not sure the guy knew what he was talking about (really bad broken English and horrible grammer) but he told me that " it would be not compatible, saddly lacks any hardware needed specifications"

When I asked him what specifications it was missing he told me "there is reason why it won't work" so I figured I would ask you all if any of you were facing the same issue, or if it works, and what I can do to make it work.

Any help is greatly appreciated,
Tech
