Hi, I am new to Bitcoin mining.  Someone offered to sell me some Antminer T17e's and S17e's for a good price.  I have read that the 17 series have a lot of quality problems.  I am familiar with PC repair and can give a go at fixing and running these machines.  

Can anyone advise whether these specific models (T17e, S17e) have the same problems and whether they are worth buying?
