Very sorry for the long reply time. I first and foremost got this as a complement to my TH8RS. For sequential shifting only. And for that it feels good. But there are a couple of niggles: It seems to be a bit picky with regards to "activation"; meaning I have to make sure the stick gets all the way back or forward in order for the switch to be activated. This caused me to miss several shift, as I have more of a gentle touch as opposed to a "brute force" approach. I like to be smooth.
There are several screws that can be adjusted, but there is no manual - neither printed nor online - and I couldn't figure out what they do (I'm not the most technical person in the world
). I will send an email to the shiftershh.es and see if they can help. I'm hoping there is some way to adjust the throw. If you want I can make a short video on the stick itself, so you can get an impression of how much tension there is. I think it's very good actually. Just the right strength. But as I said I would like to reduce the throw just a tiny bit. Maybe I'm just used to my TH8RS. The seq mode throw on that is much shorter.
All in all it feels better than the TH8RS in seq mode, which is why I got it in the first place. So now I have those two next to each other and easily switch between them.
In any case: Both these (SHH and TH8RS) are miles better than the G25 shifter. No, light years better.
I know, because I used to have the G25 myself.
