Anyone Has Had Experience With

Hey guys so I’m interested in buying some ASIC’s in BULK.

I’ve looked through for some trusty vendors & suppliers. I got a lot of options but the following website sells in bulk (used ASIC’s).

would you recommend buying from them?

Another question off topic, is it worth it buying used ASIC’s with a warranty?

Did you ever buy from them? If you did, did you have any issues?
Thanks in advance.
