Electronic Spices PG11 Polyamide Cable Gland PG Type Waterproof Pack of 50pcs

I ordered 50 pcs of pg7, pg11 and pg 13.5 from this seller. My first complaint is he purposefully mixed everything together in one plastic cover. I had to manually separate them out as shown in the image. He sent 50 pics of pg7 and pg11, but only 25 pieces of pg 13.5. He mixed in 25 pieces of other sizes without informing me. I think he hoped I would not manually count because he mixed 150 pieces together. Other main issue I have is quality. The seller is buying stock from different cable gland manufacturers with some being low quality and others being good quality. He does not just source good quality items alone, so be careful of buying. This is why in the image colors are inconsistent.
