How to get better at ultrabullet?

I'm good at blitz, bullet, but I just can't seem to get my ultrabullet rating up...
Any advice?

"Practice makes you perfect" try again.. At first my rating was 1000--1100 in ultrabullet now my rating is 1350-1500 and now I play ultrabullet everyday

Learn to premove.

Just keep playing I guess. Its all about mouse speed etc. I practiced and I am a solid 2100 with a peak of 2234. I have even beaten GM Andrew Tang and GM Zhigalko Sergei. Just keep practicing!!!

Start using the KB extension

Yes in UB only speed needed

Yeah in UB just play very fast very fast and premove also.

Lol, how can @TidyEmptyCode beat GM Andrew Tang and GM Sergei Zhigalko??

Those GMs play good ultrabullet.

Play ultra bullet games with Stockfish on Lichess just to improve your speed . In this way you can easily reach an ultra bullet rating of at least 1900.
