I'm testing several cloud miners with small investment in each one just in case they are an scam
I couldn't tell you if they are an scam or not but here is my experience until now.

Pros: Very cheap and good profit currently at 0.00006680 Mhs
You could sell your Mhs and go aout at any time
Cons:There are others with more profit/Mhs relation
Some people understand they are not trustable, I've tried myself some withdrawals whithout problems (Could provide the evidence if required)
They mine altcoins and change thm into BTC for paying, some people understand that this could damage BTC in the long term

Pros: they give you 200 Mhz for "free" testing (In order to retire or use the profit of those 200 you need to buy them real Mhz)
Very cheap and good profit
You could sell your Mhs and go out at any time
Cons:There are others with more profit/Mhs relation
They mine altcoins and change thm into BTC for paying, some people understand that this could damage BTC in the long term
Some people understand they are not trustable, I've tried myself some withdrawals whithout problems (Could provide the evidence if required)

Pros: Trustable site with long history
Market included, you could speculate with the coins and the Ghz you have and obtain additional profit from that
You mine other altcoins at the same time
Cons:Very expensive, really you loose money if only mine
