These are really smooth out of the box. I broke mine in and I am not sure how much of a difference it made, but these work very well in my 8BitDo retro keyboard. These are a VERY smooth option if you don't want to lube your switches.

When lubed, these become nearly silent. It's like having a silent switch without the soft / mushy feel that so many silent switches come with.

So smooth! Fast shipping too! I love them!

These switches are terrific and as advertised. Remarkably and consistently smooth with the usual high quality from ZealPC. The best linear switches I've tried to date.

If you don't want to deal with lubing and you just want a super smooth experience out of the box, these are well worth the cost. I'm using them on my Mode Sonnet and they sound fantastic. Very little wobble, and no spring ping.

Compared to the popular alpaca v2s (both stock):
These feel smoother but with slightly more spring ping (likely due to the snappier spring). They are also higher pitched; the return hit to the top housing has a distinct sound that I can describe best as two glass marbles bumping into each other. The pearlios unfortunately have a bit more stem wobble than alpacas.

Overall, they are a very solid linear switch. I think the alpacas are a better buy from a value standpoint especially if you plan to lube and film them. However, the unique sound and similarly great stock experience make for a compelling purchase if the price isn't a turning point for you.

I've only tested about 6 different types of switches so far, mostly linear and then some Holy Pandas, but these are by far my favorite switches so far. No lube or filming needed as they are ready to rock stock! Picked up two set of 70 and will probably buy more in the future if stock allows.

Zeals also noticed my two separate orders and combined them into one and refunded the shipping on the other. 5 star experience all around from the product to the people behind it.

Thank you!
