Sound Great but QC Issues Exist
When I first tried these, the experience was not what I had expected. The tactile bump starts as soon as you depress the stem and persists through about 90% of the downstroke. This is different from what I had become used to for tactile switches, where you feel a slight bit of travel before you hit the bump. However, now that I have been using them for a few weeks, I really enjoy typing with them. I currently have them plugged into a Keychron Q3 with a PC plate and MT3 profile keycaps. Typing on them produces a deep, popping sound. I should also mention that I am using these stock. The factory lube isn't bad at all. I tried adding my own 205 to one or two switches and did not notice any marked improvement. My one problem with the switch is that there appears to be some QC issues. I purchased five packages. Out of all those switches, about six of them have an issue where the leaf isn't triggered consistently, meaning I have to press the key a few times before it registers. Maybe I have just been lucky, but I've never purchased switches that had this issue before. Overall, I would say these are a great budget tactile for those chasing that marble-pop sound.
Cheap, Big Tactility, Long Pole
I've tried Gateron Blizzards, Glorious Pandas, Drop INVYR Pandas, Zealio V2s, Outemu Ice Clear, Durock T1, etc, and this has them all beat in terms of pure tactility. The bump starts almost immediately, which I like. The tactility is as much due to the thicker contact leafs as it is the bump on the stem, so putting stems from other tactile switches results in an interesting tactile bump. There's a weird feel when you press them at an angle, something like the stem snapping just a little between the rail the stems ride in. This was a minor issue that only became noticeable when I put it on my keychain and kept fidgeting with it for days on end. It is a long pole stem, and I didn't like the shorter travel, but that's an intentional design choice and not a flaw. I replaced the stem with TTC Brown stems, and it's a little less bumpy but with full travel and a sound I would describe as "somewhat marbly." Excellent tactility per dollar and a good base for frankenswitching.
Incredible value, great experience
I should note that I have very little experience with mechanical keyboards, having only tried the stock 45g linear switches that came with my Keychron V1 and then a set of Box Jades. The linear switches (Keychron K Pro Red) were far too light for me at 45g, so I bought the Box Jades within a couple of weeks, but the click eventually proved too much. However, I loved their tactility, so I came across the WS Heavy Tactile when searching for a more budget-oriented tactile switch that offers a fairly high 'bump' force early in the travel, and that is exactly what they deliver. So far I haven't observed any scratchiness or QC issues, and they don't feel any harder to type on than the Box Jades so far for me, but they are probably on the heavy side for those with lighter fingers. As others have noted, they are a little shorter travel than most other switches due to the long pole design, which is excellent for me, as I type much quicker on a properly stiff laptop keyboard, and didn't like 'wallowing' in the 4mm of travel with the previous switches. I haven't been able to experience high-end tactile switches with a similar feel, like the Boba U4Ts or Zealios, but after buying these I honestly can't see myself ever wanting more.
Best Heavy Tactile Switch
Love these, best switches I've ever purchased, I wish I found these sooner. The tactile bump is very crisp, at the very top, and the spring keeps its tension all the way down the actuation point. The shorter travel distance helps make the switches feel "snappy" and responsive. Feedback from the switches is nice too. Had Holy/Glorious Pandas & these make them feel like mush. Best heavy tactile switch at this price point, & honestly goes toe to toe with other high-end switches. Must try for heavy handed keyboard users. avoid if you're fingers get fatigued easily. The shorter travel distance may be a turn off for some, & it will be noticeable if you're used to 4mm. There was a slight QC issue though, two of my switches have a slight spring ping. Not noticeable in the slightest when typing though.
Switches feel and sound great.
