At the moment it is one of the World's Most powerful and efficien Litecoin miner.

Based on that:

As you can see profit per days 43.45$ and 1303$ per month! You will have a ROI of less than 2 months.

It looks a bit too good to be true. Don't you think so?

It is currently out of stock and next shipping only on 13-20 of September. You can buy used one or new but double price on eBay, amazon and other sources.
I have been looking at it and thinking all day long, reading all possible information available right now, opinions on different forums etc.

So, should i buy one? My Conclusion:

1. Litecoin community asking to Boycott this company because of shady past. https://steemitimages.com/DQmdz5fer2PE2Xd9s9DJh5EyJERhCYrbvz3WocrwVabNmRP/Screen%20Shot%202017-06-24%20at%2016.16.30.png

2. Bitmain might be selling their own old equipment. Who is giveing away something that could make you more money? Logical? You are going to buy a promise and wait another couple of months to get one.
3. Bitmain customer service is horrible! So many complains around the web. You can't expect be treating as a customer after purchasing one.
4. By end of September the difficulty on Litecoin by Bitmain mining their own equipment will be so high these things will never see a return on your investment.
5. We might simple missed the train of first buyers in May.

Best move is likely to just buy LTC and sit on it instead of giving it to Bitmain in hopes earning it back?
What do you think?
