Hi, there has been some news lately regarding the issue the Olsson Ruby been showing (https://www.youtube.com/watch?v=srtpoEE93-M) Despite the price I really like the concept of the Olsson Ruby, the only nozzle you’ll ever need. However from what I’ve read it has some problems with it, mostly: -non tapered internal passage (flow, wearing and filament change problem) -rather non-abrasively strong brass inner passage (wearing of the inner passage)The nozzle was on the sideline and I was considering purchasing until the video explaining the issues. Side note, regarding the video I would like to respectfully say that the nozzle tightening breakage problem was unfair for the manufacturer itself (although to fully mention everything, installation requirement are not labeled in the over-sized packaging box)What I really would like from your comments, those who used the Olsson Ruby what is your honest review of it? Is it really that wear resistant both from tip and inner side? Additionally is there anyone who also used EVERLAST Ruby Nozzle? Thanks 🙂 http://ift.tt/2xov6HT
