HiThe Baili 171/173 (RazoRock DE1), Baili 172/191/192 (RazoRock Tek II), Maggard V3M are all pretty much the same head - different handles/colors. These heads kind of resemble the Gillette Tech but could not, in my opinion, be mistaken for a Gillette Tech. Doesn't mean that they are bad razors - quite the contrary.
The Baili 131 is the closest Baili (appearance and geometry) to the original Gillette Tech. The Global Shave Club "Techs" and the YingJili are the same razor.
This is my opinion, based on purchasing, closely examining and shaving with these razors. YMMV.
Do you mean the Baili 131 is the same as the Yingili? And is the Black Tiger included in the “global shave club” techs?
I just got a Baili 131. 3 shaves, and I get gushers and weepers.
I have the Maagards V3M. Also gushers and weepers. Look at the blade gap on that thing. Used a Maagards mr5 handle.
Also have the Rapira. Same results.
Used Astra SP in first 2, rapira blade in rapira.
I love my pre war fat handle and NDC post war ball end techs. Astra SP blades. The 3 clones mentioned cannot hold a candle to them.
Btw, I tried the fat handle from the Gillette on the Rapira head, and found no difference.
thanks
