One of the best rudder pedals on the market. Completely made of metal, incredible construction, nothing creaks or "plays", the movement is perfectly smooth and they feel very premium to use. The difference compared to the plastic T.Flight by Thrustmaster and Pro Flight by Logitech that I have tried is evident. Very good sensitivity analysis, they "perceive" even the smallest movements, although this can be further adjusted through the software or in the sim. The braking action is also very smooth and has good feedback. It has two springs for resistance adjustment with a good range of options. They are plug and play and are immediately recognized by all major simulators (in MSFS, which I play, they are seen normally, calibrated, with their icon and name). Additionally, the base has slots for mounting on several universal bases. Their size should not scare you as, despite their height, their width is the same as most pedals.
Their unique feature, of course, is the pendular design with the pedals essentially hanging from the central column. This has positives and negatives. Firstly, because they do not run on guides like most pedals, small jams are avoided and the movement is incredibly smooth. All components are visible, cleaning is very easy, and dust does not accumulate, which can affect performance. They can also be used without any springs for minimal resistance, only with their own weight. Now, this design may not be for everyone. The pedals are clearly made to be used by resting the heel down and not the entire foot on them. Even at their lowest inclination, having the foot permanently on top is not the most comfortable. I prefer the heel down as I feel I have more precise control, and it also seems more realistic for GA planes or fighters. If you prefer to press with the entire sole or "rest" your foot on the pedal, it may not suit you. Also, because they are pendular, each pedal is essentially autonomous and the distance between your feet does not change as you press them, thus avoiding unwanted small rotational movements and strains on the knees.
As for the negatives of the pendular design, because you do not press on the pedals to hold them with the weight of your feet to a certain extent, if they are not fixed somewhere or if there is no carpet underneath them, they move completely. Especially on tiles, it doesn't take much effort for them to slide despite their weight. Also, without shoes (even with socks), you will feel your toes entering the huge holes in the pedals many times, slightly losing control. Finally, adjusting the springs and the inclination of the pedals, although easy to do, require tools (provided in the package), so it is difficult to change them while playing.
Overall, they are a fantastic choice if you prefer this style of pedals, and the only negative is the price. Although they are incredibly well-made, there are cheaper alternatives made of metal with equally good performance (MFG Crosswind, Vipril ACE, etc.)
