    Have the Blue Xulin and would've bought the Red too if it was available. I just received more of the 2.0, 3.5 and can't really tell the difference between all of the pens tbh. Haven't tried my Gansulin yet but it seems I might have to use that one so I can micro-dose reta with my wife in small increments like 2-4 units. I just hate having to save the Gansulin for weekly injections like reta. V4 says accurate micro-dosing so I'll likely try that one too at some point. Can't believe I waited this long to try pens, what a giant dummy...

      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?

        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.

                    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?
