I’ve been hands-on with the SK621 for about a month. I’ve used it for everything from typing, media controls, gaming and everyday use in general. In fact, this entire review was written on the SK621. At first, I thought I’d have to get used to the size. However, the 60% layout size of the SK621 is almost the exact same size as the keyboard on my Lenovo ThinkPad. So, getting used to the size of the SK621 didn’t take any time at all. In fact, it felt natural from the start.
I do most of my writing on my laptop, so the key caps feel natural and are a good size. I do like the slight contour to the keycaps as they feel more comfortable than traditional chicklet style keycaps. If you’re a fan of Cherry MX Reds, then you’ll love the feel of typing on the SK621, as they use Cherry MX Red low profile switches. The low profile switches feel identical to the traditional Cherry MX Reds. However, the actuation distance is slightly shorter. Although I don’t think its something the average user would notice.
I spent a few hours playing different games using the SK621. As I am used to gaming on my laptop, I had little to no issues adapting to the 60% layout of the SK621 for gaming. I really enjoyed gaming with the SK621. Especially when gaming on my laptop. The keyboard on the ThinkPad has always been the one downside to the laptop for me. Now, the SK621 lives in my laptop bag and gets used any time the laptop does.
The SK621 can be connected wireless through Bluetooth 4.0 The wireless connectivity makes the SK621 great for use on a media PC. We have a home theater PC set up in the living room and connected to a PLEX server. The SK621 works great as a remote control for the HTPC. The battery life on the SK621 is amazing. I left the SK621 on, in wireless mode with the RGB lighting going one morning. I left the house at about 8 am and returned at around 930 pm. The SK621 was still on, with the RGB lighting on as well. I charged it overnight and disabled the RGB lighting. Since then, it’s been on my desk, paired to both my cell phone and home theater PC. It’s been about three weeks and I have yet to charge the SK621 yet. Cooler Master advertises up to a four-month battery life with no lighting. So, we’ll see how long it lasts. But even when the battery does die, you can just plug it in and use it in wired mode while it charges.
The way I use the SK621 the most by far is paired with my LQ Q7+ and my iPhone 7+. I keep it set up at my work and use the SK621 for searching the internet, social media, YouTube and even Microsoft Word. The SK621 allows you to pair it with up to three different devices at the same time which is yet another great feature of this keyboard.
