A few month ago, I bought an HSK+ 4K Wireless (or the "Plus") and I liked it a lot. I liked learning how to use a fingertip grip and it has improved my aim and overall gaming performance. But the Plus had a few drawbacks that led me to switch back to a Viper as my main mouse.
Fast forward a few months and additionally, I decided to try the HSK Pro 4K Wireless (or the "Pro") as well and received it in the mail a few days ago. This is, without doubt, my favorite mouse I've ever used. It's even smaller and lighter, which allows for a true fingertip experience. But what's most exciting is that the upgraded internals used for the Pro vs. the Plus that I already had make a huge difference. There are three major improvements:
1) The left-click and right-click buttons on the new Pro are a lot more crisp and "clicky". I felt like the Plus left/right-click buttons were a little bit "mushy" or "muddy" feeling, but the Pro is the opposite. Clicks feel great and sharp! Huge upgrade! But not just those buttons, the side buttons are MUCH better as well. They are slightly more separated and much easier to locate independently of each other. They are also perfectly placed and size.... But on top of that, they too, were sort of mushy on the Plus I have but very, very crisp on the new Pro.
2) Also, the click latency is noticeably less for the Pro than it was for my Plus. I don't have an "official" way to test for click latency, but I'm very in tune to it and am able to test it with some degree of certainty by doing certain reflex aim-training tests I have saved in various aim-trainers. When latency is bad, it always shows in my scores, and when it's good, my scores go up. In this case, with the Pro, my scores are the highest ever and I'm big on mice with low click latency, so my high score using this mouse means the latency is even better than 2 other mice I have that are known for the lowest latency in the industry. Not only that, but in game, the latency using the Pro feels so much lower than it did using my Plus.
3) Lastly, the improved tracking sensor is noticeable, and I didn't expect it to be. The Pro uses the PMW 3395 and I think the Plus I have used the 3390. I didn't expect to notice a difference and I'm not 100% sure I do, but I'm about 98% sure that the tracking does, indeed, feel more accurate, a bit more snappy, and less glitchy.
All of that being said, I'm not trying to sell anyone on the Pro over the Plus, because I believe the current version of the Plus has the same upgraded internals now as well.
My overall point is that this new mouse is seriously as high-quality as it gets. It's a work of art. The Pro is the absolute perfect fingertip mouse and with these premium internals, there are no drawbacks at all in comparison with any other mouse on the market. I'm really happy I decided to try the Pro because I had no idea how much of an improvement it would be with the upgrades, nor did I realize how much easier it is to actually make a fingertip grip work by using the reduced size and weight of the Pro.
A seriously applaud G-Wolves, they have created a masterpiece! They have not only created a masterpiece, but they keep finding ways to take perfection to a new level and that's what makes this mouse so special. The attention to detail deserves commending and recommending. I don't write a lot of reviews, but this mouse warranted a thoughtful review, I hope it helps someone out there.
