I can barely find anything about them, which usually means that the smarter thing to do is to stay the hell away from them.

There's a couple threads about them, but none are conclusive.

https://bitcointalk.org/index.php?topic=5118346.0 user more or less states he didn't receive his miner.

Also what's interesting is that they have 103 ratings on https://www.cryptocompare.com/mining/coin-mining-central/
100 being 5 stars, 3 ratings of 3 stars.. Odd.

You'd think that with 100 reviews on CC, they'd atleast have some more discussion around them on other sites/forums/the internet in general, as atleast a couple thousand people have bought miners from them
(I'm assuming that only 1 in 10 leaves a review on Cryptocompare, which i think is still generous, considering almost no one leaves reviews nowadays, unless the product is shit/a scam.)
But no, there's absolutely nothing to be found about them.

I'd stay away.
