Everything points to KIR being a scam. No phone, no address, private domain registration through a proxy, no business certificate, a lot of positive paid reviews on low quality sites, very few real customer reviews on respected sites (most saying they never received the product), payment only available through anonymous channels, no access to developers or management… and of course, the company name is “Kir” - which means “Penis”.
So far I haven't come across a single person who has paid and received the product. I recommend not sending them any PM or BTC, unless it's as a gift.
