Hi, this product is a scam.
I purchased over April 2018 and have never received anything or a refund. If you check out the comments on their Kickstarter page, you'll see I'm not the only one.

I've had one email from them to say they will pass on my details to their accounts dept. after I requested a refund but that was 6 months ago and no other relies.
Hope that helps.
