They work fine, but they're quite long and mate with the base bar in an unusual way, both encircling it and going inside it. As a result, they will only work on round base bars "handles" of 23.6 diameter. You've got to have 55mm of that round bar inside the lever, so it will also need to be straight for at least that length.

Okay. So it does look like they would work on the Vision TFA bars then. Honestly I think they kind of look better than the super bulgy SRAM and shimano ones but I might be underestimating how much they increase the radius of the bars.

I have no idea if they will fit on those bars or not.

These are not small. The diameter is roughly comparable to the Shimano unit, but it's 3x (ish) longer.
