Good pre-lubed silent switches

Been tired of having to open switches and lube them, as fun as it is. These are a very welcome addition to my switch collection and highly recommend them for anyone interested in trying new silent switches 👍🏽

We love these switches stock as well! Glad you like 'em :)

Great silent linear switches but with possible R3 interference?

The Haimu Heartbeat Silent Linears are the first silent linear switches I've tried and I was pleasantly surprised. The switches come with a good amount of factory lube on the stem legs, the slider rails, and the bottom housing. They use a standard 15mm 65g spring which also came factory lubed.

They are very smooth stock. The top housing was very tight, so I didn't feel like they needed to be filmed. They are also incredibly quiet without feeling very mushy. I think the stem design helps with the mushiness and the holes on the bottom housing help with making the switch quieter, as pointed out by reviewers such as Maker Mods and ThereminGoat.

One issue I came across is that there seems to be some interference with my keycaps and the switches in the R3 row. I had Cherry-profile PBTFans WOB on the switches when I was using them. For example, when I typed on the keys on R3, it sounded like I was hitting the top housings of the switches. However, when I would type on R1, R2, and R4, the switches would be super silent with no issues. This doesn't seem to happen on any other switches I have.

Overall, these are very good silent linear switches and I would definitely recommend them to people looking smooth and silent experience. I think there has to be some more testing with other Cherry-profile keycaps to see if anyone else comes across the same issue.
