Partially faulty- unable to set current limit

I got a package of 5 and was not able to set the current limit on any of them. I adjusted the current set potentiometer from one extreme to the other, but the short circuit current remained stuck at 2.5+ Amps. Can not be used for battery charging, but only as variable voltage power supplies. Can't argue with a 4.5 star rating - maybe I just got some from a bad batch.?

Pros

LM2596 buck converter stably output, voltage conversion efficiency is up to 96%. The output voltage is 1.25V-37V (continuously adjustable, the input voltage must be 1V higher than the output voltage),the output current is 2A (normal and stable), the maximum is 3A.

Cons

May not be suitable for use with sensitive electronics
