There is not a lot of room for negativity on the Rosélios/Healios switch: it’s quiet, it’s smooth, and it’s pretty. Zeal has conducted vast amounts of R&D on each of his switches for them to be the quality that they are, and it shows. Currently running in my Aanzee, the Rosélios is the quietest switch that I’ve had the chance to use, with excellent smoothness to boot. The only downside is the high price per-switch, and this can deter a number of people from trying them out, especially foreign buyers dealing with currency conversion. Then again, some things are worth the expenditure, and I would say this certainly is.
