ZERO STARS ----- Very poor quality control.. After having to unsolder and replace 4 out of ten units. I decided to build a small test fixture to test these before I soldered them into my circuits. After testing 10 units and having three failures, I decided to stop wasting my time. I cannot spend my time performing 100% testing of a suppliers product. then take a risk of installing this in my product, I've used 100s of these from another vendor and have had ZERO failures. looks like I'll switch back..
