Oh you just had to post this and remind me.....haha. They don't exist that I know of, there was a kickstarter for this back in 2015 I believe and I backed it, they had all the funding and failed to ever deliver the final product with not much of an explanation. No refund and they even kept my shipping fees, it was pretty lame and probably a scam of sorts some of the backers believe. There is an original one that is still for sale that isn't as cool and it was an established company so I felt pretty confident backing it. I was really bummed to not only loose the money but not get the product, I was looking forward to it.
