Still working good for you? Do I have to pay so much for a kiwi? I think others are way cheaper but not sure if they work well.
I'm using UpRev's Cipher with my laptop. It's not small & compact, but it works awesome. Consider saving $300 more and buy UpRev Standard to tune your Z and have Cipher to use when you want.
I posted a video of Cipher logging for those who haven't seen it.
