We've ranked it #9 out of 46 in this category. It's in the top quartile of the category, which is where most buyers should be looking.
What It Feels Like to Type On
The Mechanical switches define how this keyboard feels in use. Switch choice is personal - what feels great to one typist can feel wrong to another, so it's worth knowing what category these fall into before committing. In this price tier, you should expect aluminum top plates, doubleshot or PBT keycaps, and per-key RGB. If those aren't here, the price is hard to justify.
Worth noting on the GravaStar Mercury K1 Pro specifically - reviews repeatedly flag "Unique sci-fi design" as a standout.
