I've owned the Ultra's, the FPS Freek Black Ops III's, and now these. Loved the Ultra's (only used one on the right analog stick), good quality and grip. The BO3 Freek's were ""nice"", but didn't seem to on par with the quality you'd expect from KF. The rubber was coming off the left piece after only a couple weeks and that one was very loose. These are the best Freeks I've owned. The strange, yet very effective, grip is amazing. They come with a short one for the left stick, mainly for grip. And a tall one for the right, for accuracy when in medium to long range gun fights in first person shooters (FPS). They take a bit of time to get used to if you've never used any of these. But, once you find what sensitivity is comfortable and accurate for you, these will make a world of difference in your performance. And I'm not a pro gamer, by any means. But they do make games like Call of Duty much more fun and competitive.
