I ordered two pairs, poked on the blue and asked the seller to send another size (smaller) in the end some blue. As a result, not the size I need. I think the seller could clarify if he had something unclear in my request.
Excellent quality, well crimped (you need crimping pliers for connectors with insulation) and perfectly seated with a hairdryer, the glue is that provides waterproofing for 100%. Sits dead with proper crimping.
