Yes I got them, Tantan sent the wrong handlebars so I replaced with HBR17.
I have 100x360 with adapter for SL8. Finish is definitely better than the Rapide clone although there were some sharp edges where the hoses exit by the shifters (inside edge, scraping on the hoses), but I got it sanded. Also gave feedback to Wendy @ LC about it. Top cap sits better than on the clone. To me they feel nice and stiff, but I'm also a quite small and light guy (62kg) so I'm generally not worried. Besides being available in narrow size they have a compact geometry for reach and drops that suit me and I generally like the shape and curves of the bars.
Bars only weighed like 310g, with top cap, spacers, computer mount and everything it was about 350g. Came delivered very well packaged. Handlebars wrapped in a nice foam tube and box filled with more foam.
Computer mount has an unusual 3-bolt attachment so I don't think there are really any options to have it replaced with something else unless you get it designed and printed yourself. I had issues with front brake vibrations and my Garmin unit on the Rapide clone bars, where it would warn for an incident after using front brake while stopping the bike. I got it sorted with installing 3mm soft foam that I put between the mount and the Garmin adapter (just squeeeeezed with the screws). I did the same from start with these bars and the computer mount, so I have no idea if these would have the same issue without the foam.
Don't have that much to compare with, before the SL8 clone I had a repaired frame from 2013 or so, with round alu bars. But I like this one, to me it feels good and it looks good.
Pictures from when I had just installed them on the bike.
