I had a bit of an issue but what matters is the response, the guys went above and beyond to put things right and sent me a free item to make up for it. I’ve had a couple of orders from them now and apart from one everything has been spot on but that was dealt with quickly without any fuss. This is a genuine review and they deserve the praise so well done Beenu, Tom and the team

I’ve contacted support multiple times with no response. Haven’t received any tracking number or an email to say it been shipped. I haven’t received anything. Think it’s a scam.
