I ordered blue and green diodes. There are no problems with the green ones. But the blue ones have a different rating (barely light up at 3V) and a different polarity. The special feature of the diode is that I can't install them any other way!! ! On the left in the photo, there is a green one; as you can see, it has 4 legs, and it can be placed in any way you like. The one on the right is blue, and there is only one installation option. I am VERY disappointed!! !

The package took a long time to arrive but it was worth it, the product is just as described, the communication with the seller has been very good, I will continue looking at products from their store, I might find more interesting items.
