Hi.

I am looking to by some miners and have found a used Antminer S7 at a reasonable price.

I have searched but can't find the life expectancy of the products. As its second hand it could have been used for the last 2 years so is it likely to break anytime soon?

Is there any other reason why they may not work or am I ok to buy a second hand S7?

Thank you for any help.
