Unlocked a deal on Evofox Katana S Mini Wireless at around 1300. But, it seems DOUBTFUL now.
Newbie here.
I recently bought a laptop and was looking for my first MK. I kept my budget pretty low at around 1500 because I was unsure whether I'll like the typing experience on a MK. I was eyeing a few membrane keyboards and the Katana Mini S wired variant. During the Flipkart sale, after bundling all the products and applying a few more discounts (Buy More Save More and Superocoins 100x value), I grabbed the wireless variant, which to me seemed like a deal at 1.3k. So, I went ahead and ordered it.
Now comes the funny part: the seller says it will take almost 15 days to get my order delivered, which to me is strange. For context, I live in a tier 1 city, and none of my deliveries take this amount of time unless something goes wrong.
Is it really common for keyboards to take this much time, or will I get pranked?
Another question is: Are membrane keyboards really that unreliable when compared with the mechanical ones? The reason being, I have used (or abused) my old laptop keyboard and got it damaged/replaced 2 freaking times. I do touch type and avg around 90 wpm.
TIA.
Happy Typing!!
