    Why are the red ones better than the blue ones? What am I missing? I own the blue one and love it.

      They arent. Same mechanism. Xulin did a limited run of reds.

            Just ordered the V4 from here- but was really interested in the Red Xulin 3(I saw @randy had said they were done) so I'll wait for a non-blue one for him to put on the site- but anyone have both to give me a comparison?

              I've got a blue something else- just got a really nice V4 from here- so red helps with my color coded life 🙂

                I bought a V4 and a Xulin 3.

                I see in the other thread you recommend the Somang Novofine 32G 0.23x6mm for the V4.

                What needles do you recommend for the Xulin 3?
