Go for it, seems well made with pretty solid review. If you want to play it safe check out the riro one https://it.aliexpress.com/item/1005009255569255.html

Going from a 70g stem to 210g is quite a lot of 'playing it safe'
I'd consider getting one of these stems if they weren't so dedicated to being Darimo knock offs, why do they insist on adding the logos...

[POTOOOOOOOO]

The legit Darimo I had in 110mm was a bendy pile of crap, so I don’t think a copy is going to be any better.
Nice looking stems, but ultimately I’d take the small weight penalty and get an UNO

I would have all kinds of concerns about that stem. Get an Uno.
