"BALUGOEU " carbon seatpost

[Waki]

Hi guys, new member here, I am sure lots of folk will post interesting stuff here and I am new to chinese stuff, but after seein plenty videos and having some small things already, iam sure there are gems.

Is anybody having experience with this Specilazed CG-R clone? https://shorturl.at/5OdxO Does it really flex for bump reduction? Or stuff from Canyon/Ergon "double leaf" is only the good option - and maybe some Chinese alternative is also available. Thanks! Looks tempting even due weight limit of 150kg, I am 100-110 kg guy without bike and backpack.
