I like using capacitive keyboard rather than a mechanical keyboard, but the fact is I often take my MacBook and walk around. It is very hard for me to sit in front of my desk to use my capacitive keyboard.

I have a mechanical noppoo nano 75-s. Unfortunately for me it is not a wireless keyboard, so the cable connecting to the PC got damaged over time and now it’s impossible to find a replacement.

This keyboard is a traditional mechanical keyboard. It was one of my absolute best keyboards and if not for the cable issue, odds are I would still be using it today. I bought it over a decade ago for around 150$ in a discount.

Why is there so big of the price difference on their official website?

It is rather common for stores to have online only discounts in order to drive engagement on the website and create a user habit of frequently checking it. This should not affect your judgement.

Right now it feels fine, but I don’t know if it will still feel the same a month from now or not? Like my MX 8100 felt the same after it accumulated a huge amount of dust.

From my limited experience, the Corsair is fairly well known, that should do you well for years to come. In the event that a key gets damage, you can replace it, and you can also replace the switches:

This will obviously void the warranty though:

Do I keep this keyboard or bring the regular variant of it? Has anyone used any low profile mechanical keyboard?

I would go for the one that feels the most comfortable and is easier to repair. I don’t know how easier/harder it is to repair the low profile variant, but I assume (with a grain of salt) it can’t be that much harder.

I am currently using a low-profile mechanical keyboard - Redragon K621 TKL with red switches. It is my second mechanical keyboard, the first one was the cheapest TKL I could find to test whether I even liked mechanical keyboards.

Chose this model as it was significantly cheaper than the generally recommended Logitech low-profile option that costs around 200 usd. Checked out the Corsair as well, but I think was turned off by some bad reviews, and it was more expensive as well.

I chose a low-profile as it is easier/faster to type on it. Especially coming from using laptops exclusively for many years.

Though I think I preferred the brown switches, unfortunately, this keyboard only comes with reds.
