I have not investigated offerings on Amazon and I have mostly bought them from AliExpress or sometimes Ebay (the CJB in particular) but that was some years ago, so I am not commenting on razors that might be new designs in the past few years. In my experience the clones shave fine. The blade holding mechanism is slightly different from Feather and the tolerances are not as good. Larger gaps where the pieces fit together, but nothing that really affects the shave performance. I had a pin fall out of one razor and have not yet put it back together as I need to get a different needle nose pliers and/or better vision as it is difficult to position and press back in place. I don't think that would ever happen with a Feather or Kai razor but have had a couple of loose pins with these cheaply assembled razors.It’s been a few years since I was into shaving with straight razors. What’s the current status of feather artist club clones? Is there any one in particular that people are going with? I am an Amazon prime member. Are there any to be had there or are people getting them off aliexpress?
If one were a committed shavette user I would recommend buying a Feather and enjoy it for years and years. With the JPY devaluation relative to the USD, they are less expensive than in the past, making them easier to recommend them over AliExpress offerings. IMO one will enjoy having the higher quality item if they are using it all the time. In that train of thought one could justify a more exclusive product like the Tedalus Essence.
But if one were just starting out with shavettes and not sure they will stick with the artist club blade format or had other budget priorities, then a clone is a fine way to start.
