Aliaz did / does have something of a questionable reputation in many parts.
If you look at older posts on them, there are complaints about the minimal tactility. Almost like a linear.
But the bigger complaint is the springs. Numerous people commented on how noisy the springs are. It’s supposed to be a silent switch, but you can hear the spring crunch!
Modders were frustrated that the switch doesn’t seem to take to lube well, meaning that you can’t change the smoothness or sound profile as much as you’d like. But at least you can change the spring.
A lot of the early dissatisfaction from Aliaz comes from the way it was ‘marketed.’ It was a “silent tactile” that costs .60 cents or more [in 2018 or so] and so people had high hopes for it. But the stem isn’t much different than a Gateron Brown, specifically a Gateron Silent Brown. There were a lot of comparisons made. People looked for the MX Clear influence in the stem, but it was hard to locate [early talk had it as a Clear-ish stem].
So people basically saw it as an overpriced Gateron Silent Brown. I’ve tried some Gat Silent Brown, though, and I don’t think it’s as quiet at Aliaz. Just replace the spring and you’re good-to-go.
