I used to have a HT-S2, yeah. Haven't tried the HTS ultra though. I have a ASUS Harpe Ace Mini that, shape-wise, I like better than the OP1 or HT-S2. Another option is the Gwolves HTR, HTX mini/HTX ultra or maybe the Finalmouse small. I don't really enjoy the small fingertip oriented mice, but I do feel that Gwolves has the most options and best options for small mice out there.
I have used ROG Harpe Ace Mini for nearly 6 months and i loved it, great small shape and good gaming experience for me. I have now switched to VV3 Pro recently because i bought it on sale but to be honest i didnt really feel a major difference between them other than shape. You can find better mice than ASUS mice for sure but they are still worth it imo. Feel free to ask me any questions and i will try my best to answer!
If you fingertip and want a short mouse with narrow sides, Harpe ace mini makes alot of sense. Beast X and Beast X Pro also fit that style if youre okay with very light mice. Viper Mini or Cobra are also solid options if you want something compact without going full fingertip-only. Whats your hand size?
Get the harpe ace mini if you prefer small or you want to try a small mouse otherwise get the gpx2 or you can save your money and repair your existing gpx.
ROG harpe core mini a mouse With a hotswap feature meaning you change the switches easily without soldering also this mouse is compatible with optical switch not just mechanical I recommend this mouse and buy the lightest switch available on the market
Op18k v2 ROG harpe core mini These are not left handed mice but they have a hotswap feature so you can replace the switches easily without soldering
I got the Harpe Ace mini about 2 weeks ago and loving it so far.
Have the ACE Mini also :)
