X-Raypad Obsidian PRO Air - Universal Donuts (Grey)

Meh, regular ones are better then the donuts

Excellent for use with a skypad. The almost linear increase in control relative to the number of donuts used makes these highly tunable.

The increased surface area and distributed loading pattern means the UHMWPE feet have exceptional wear resistance - orders of magnitude higher than the PTFE equivalent.

The sound is louder than typical PTFE but it has a lower pitch, and you're not paying for that silence by depositing a layer of water resistant PTFE on your pad.

There are 2 potential caveats to these that must be considered:

Firstly, the diameter is large - slightly larger than I expected. It's large enough that it does not actually fit perfectly in the skate well on my Terra Pro. As such I would assume the same is true for a g-pro or a g703 and could be an issue for the back skate well on a superlight also. The skates do adhere, and work well, but I have a feeling these feet will be more prone to moving about under the mouse over time due to not being a perfect fit. If they reduced the diameter by 1mm, maybe even less, they would be perfect.

Second, keep in mind with the donut shape the area of edge contact is increased substantially. While the hole gives somewhere for contaminants to escape to, overall you're just doing a much more thorough job of scrubbing your mousepad with these feet and as such you must anticipate the associated increase in particulate accumulation. Frequently clean your pad with Iso and there is no issue.

Overall these are exceptional feet with precisely adjustable control. If they just reduced the diameter a tiny amount they would enter "perfect" category - currently 4.5*

Amazing product dead silent and super smooth

Good but wish there was more friction.

Good control/speed balance on artisan raiden. Testing on glass and another pad today.
