great silent switch

smooth, quiet, no mushiness

these are so beautiful! what a neat piece of engineering. they are extremely quiet, but despite this they feel a lot like non-silent switches. they have a very gentle landing and lack the mushy feel of rubber damping. i suspect these would be useful to people who suffer from RSI as well as those who want a quieter keyboard. they have, not a scratch, but a very gentle powdery feel. manual lube diminishes this somewhat, though i don't feel it is necessary. the factory lube seems decent. i have not had mine long and cannot yet vouch for how they break in, but they seem quite well made.

Great switches for a new mechanical keyboard user

I only recently got into the mechanical keyboard game, and these switches are awesome. I bought a Keychron C2 with the default Gateron reds, which I left at my parents' house for use when working remotely over the holidays. Months later, I bought myself a barebone Keychron V5 to use at home, but I wanted something quieter, and a friend recommended these. Couldn't be happier. So on my next family visit, I ordered another set of these and replaced the Gateron reds. Huge improvement. Not only do I much prefer the sound of the Heartbeat Silent Linears, but they feel far less wobbly.

Anyway, I can't claim to have sampled all the quiet linear switches on the market, but I'm a very happy repeat buyer of these switches. The price point is awesome, delivery was quick (I'm on the US east coast), and none of the switches have been faulty.
