Great Quality Product These are ~1" risers and they fit perfectly on my Adv 250 (2022 model). I have been using them for about a month and I would say they definitely make my ride more upright and comfortable. After tweaking with the handlebars for more than 3 years, I realised that I needed the risers and these are the perfect addition to my bike.
Note: Viaterra gears themselves say that we don't need to change the Clutch Cable Or Throttle cable after installing these and also after talking to some other riders, they also said the same thing. But for me the scenario was different and on moving the handlebar upto the right & left locking positions, my cables were streching. Hence, I had to change the cables.
