I have used them and did received the goods as well. The goods were Note 7 which was involved in a worldwide battery recall debacle. I was given a big run around and told things from Supero that weren't true like 'The dual SIM model is not part of the global recall so you are not affected' which was not true. It took a lot of push back from me for them to finally return the units and get my refund. 

But you did get the goods at the price and quality as you initially expected ? Just follow up service wasnt good ? 

Thanks for that. So warranty claims could be an issue?

I presume they are not located in NZ and send from hong kong or similar?

arthuritus: I prepaid for a xiaomi laptop with Supero and as an additional service, they installed an english operating system for me. This service (less than $100) was billed on a post-pay basis, ie I was not expected to have paid before they shipped the product. A few working days later, I had received the laptop along with an aggressive email that quickly escalated to accusations of theft and threats of legal action within just one week. I paid promptly, but I was shocked at how incredibly rude and unreasonable they were.   Fast forward 6 months, and my laptop's trackpad stops working despite efforts to update drivers etc. I have sent multiple emails (they have no phone number) but they are simply ignoring me and refusing to engage in the warranty claim process.   Buy from Supero at your peril. 

Yes I have also had a run in with them after they advertised something that i purchased, had it update "waiting for courier" then after having it sit at that status for a couple of days to be told that they don't have any and won't get it in for weeks.  After telling them not to list stock they don't have and how I was out of pocket due to this they tried to tell me to read the t&c's and not to tell others about the issues with them.  I asked which T&C has the gag order attached to it and never got a reply back.

I would suggest you file papers with the disputes tribunal (can be done online).  Request a full refund as they have not even tried to fix it and then throw  another $500 on top of the amount for "damages".

Personally I wouldn't touch them with a 40 foot barge pole; it claims its ACN is 612225180 yet when I search the Australian companies office there is nothing listed with that number. The fact that won't even list an actual location from where they're operating should send off alarm bells.
