Elecom Huge Plus... bought into the hype but not impressed
I'll start with the most egregious issue: when you left click, it also yields a right wheel scroll press. I confirmed it's a hardware issue across 2 computers, different settings, different OS, no MouseAssistant, etc. The only way I could get rid of this is to disable the right scroll button in the Mouse Assistant software. Minor annoyance for someone who doesn't enjoy the tilting scroll wheels in general (like me), but this would be a dealbreaker for someone who does.
Secondly it's the ergonomics. I have small hands (I was under the impression this mouse would suit me) and the scroll wheel is just badly placed. It's something I came across during my investigation before buying but didn't think with small hands it would be an issue.
But the buttons are so inconsistent! For example the Forward button is very hard to press when I press it exactly where my thumb lands (eg towards the front corner) but when I curl my thumb back so that it's pressing more where the arrow is, it becomes easy to press. The scroll wheel button is stupidly hard to press no matter what you do. So much so that I just remapped it to the Fn3 button (two buttons already lost: scroll right, wheel click).
Now this might be contentious but the roller bearings aren't the cure-all I keep reading about. Yes they are very smooth when already rolling but the stiction issue is still there. It's a lot more sticky than my Logitech m575 or Ergo S statically.
Actually the fact that the kinetic friction is so low only highlights how much static friction there is, because during slow diagonal movements I get staircases. Cleaning it doesn't seem to help too much and there is a break-in period after every cleaning which is annoying.
Then there's the finish. It just doesn't feel like a usd100+ product. This is a minor thing but the rubbery cover wasn't stuck properly and looks like it's peeling (it's not, but that's what it looks like). The wheel looks tacky and cheap.
The next gripe is personal preference, I just happened to learn it with this particular mouse. But I didn't really get along with such a heavy ball. It's cool for momentum but the same momentum makes me overshoot my movements all the time.
Overall, not impressed. I liked the H/L switch, the BT/USB switch and the DPI buttons. The shape is cool (thing is HUGE lol). I'm keeping it next to my Logitech Ergo S as an alt input device just to switch it up every few hours of work.
Fix the bugs, give me an ergo tilting option (it's a bit flat), reduce the price and I might look at it again but until then I'm not trying Elecom again (sorry guys).
