I have posted a review of Hiwa on youtube. Kavasseur has not reviewed the GHK Hiwa although has reviewed Hiwa from other vendors. I have his blessing to do these reviews, I made a point of asking him and he is completely cool with it. Sorry about the quality in this video, I'm not sure why it's so bad, possibly to do with the lighting. I'll try harder next time. I believe there will be a next time, I'm actually enjoying doing these. I'd love some feedback one way or the other about this.
