Brand X is good, but I would make sure you put some suitable grease in when fitting the remote cable (I used shimano cable grease to fit a replacement after a week or two, the original was barely moving. This period had to be fair involved the bike sitting out in the rain during a camping trip, but gear cables etc. did not experience the same -replacement cable has been fine since).
Apart from that, 1x lever works well, no issues with anything, and we were able to fine tune the drop with a oneup dropper spacer thingy. I need to check how much it weighs before deciding whether to get myself one to replace my severely scored Reverb.
