This is an upgrade from the prior version with a huge heatsink attached.

Positives:

  • The speed runs from 1.6 to 2.2 overclocked.
  • Yes - it performs as promised.
  • can be easily chained to same control system or computer

Negatives:

  • If using a USB port hub - you will need to skip a slot each time because of the oversized heatsinks.
  • no other major issues

 

Price from $18 to $22 dollars each.
