Reads like it is translated from non English, and the About Us has:
"Benchmademkts is located in West Los Angeles, California"
Yet from the same page:
"Company Address: 136 W 3rd St, 10037, New York, 43, US"
Doesn't match up, and no one from the U.S. would write an address like that.
Foreign doesn't automatically mean scam, but it's clearly not what it claims to be.
The email is also @outlook, which screams single person company or scam
Also tried clicking one of their info pages randomly, picked the one on Elmax. I highlighted a chunk and Googled, and it appears to be a word for word ripoff from BladeOps.
I'd steer clear.
