I went this route and have mixed feelings about it. It is legitimate and I have received payouts, but there are other issues.

They send the sats when you get to 400,000. When my miner was set up about 9 or 10 months ago and started hashing, I was getting them about 2 months apart (3 payouts so far). The last one was 4 months ago and I'm still not close to the 400k for the next one. This is because of a lot of down time due to maintenance (not sure what kind of maintenance) and and electricity curtailments (Paraguay). In their defense, they prorate the monthly charges, so the ROI doesn't necessarily take a big hit.

You also cannot choose which pool to point your hash toward. They seem to work with Luxor exclusively. It's a smaller pool relatively speaking, so for now this is probably alright and helps to take some power from the big 3 or 4 other pools.

Overall, it has its benefits, but be aware that there are tradeoffs to consider.
