Poor construction
Work well if you can get them not to disintegrate. Very poor construction, they measure as said on a multimeter, so the specs are correct, but suitable only for soldering once, the legs don’t seem to like solder and are too short to properly use. Half of them literally broke when soldering at a low temperature or had a broken secondary windingFrom the pack I’d say 2/3 were usable
