Learn how to fit Corepad Skatez G+ ONYX Universal Mini Donuts, choose between 1.00mm and 0.85mm thickness, and avoid the mistakes that ruin glide on glass pads.
Quick answer
Corepad Skatez G+ ONYX Universal Mini Donuts are dome-shaped PTFE dots backed with PORON foam, and they are recommended for glass mousepads. Pick the 1.00mm set when you want more clearance and a firmer, more controlled contact; pick 0.85mm when you want the mouse to sit lower and feel closer to a standard skate. Install them only after removing both layers of the stock feet.
What makes G+ Mini Donuts different from standard skates
A standard skate is a flat PTFE strip cut to the outline of your mouse base. The G+ Mini Donut is a small dome: the PTFE is convex, curving outward, and it sits on a PORON foam layer. That dome shape is the reason Corepad recommends these for glass pads. On a hard, low-friction surface, a flat skate can hydroplane or feel vague; the domed contact patch keeps a defined point of pressure so the mouse still communicates stopping power and control.
The ONYX compound is black refined PTFE, described by Corepad as balanced: increased durability, smooth gliding, good control, and good stopping power. It is not a pure speed skate and not a pure control skate. If you have used Corepad CTRL skates, which are heat-treated to be slightly slower and more controllable, ONYX sits on the other side of that tradeoff while still staying usable on fabric.
Choosing 1.00mm or 0.85mm before you peel anything
The thickness choice is a clearance choice, not a quality choice. Both thicknesses use the same ONYX PTFE and the same dome concept. A 1.00mm donut lifts the mouse base higher off the pad, which matters if your mouse has a recessed sensor lens or if you are adding dots on top of an existing base plate. The 0.85mm option sits lower, so the mouse feels less perched and the sensor-to-pad distance stays closer to what you had with stock feet.
There is no universal answer here because Corepad does not publish a sensor-lift specification for these donuts, and the correct height depends on your mouse and pad. If you are unsure, start with 0.85mm on a glass pad and only move up to 1.00mm if you get scraping, inconsistent tracking, or you are stacking over a modded base.
Where universal fit actually applies
Universal means the donuts are not pre-cut to one mouse outline, so you place them yourself. That is an advantage on unusual bases, small mice, and modded shells where no pre-cut set exists. It is a disadvantage if you want a guaranteed factory fit with no measuring. Before buying, check that your mouse base has enough flat real estate around the sensor for four to six donuts without overlapping screw holes, the sensor opening, or the battery door.
If your mouse does have a dedicated pre-cut option, a cut set removes the placement variable entirely. For example, Corepad Skatez for the Razer Cobra Wireless come as two full sets at 0.80mm, and Corepad Skatez CTRL for the Razer Viper V2 Pro are pre-shaped and heat-treated for a slightly slower, more controlled feel. Universal donuts make more sense when no cut set exists or when you want to tune contact points yourself.
Prepping the base so the foam actually bonds
PORON foam adheres to a clean, flat surface. Any residual adhesive from old feet will create a high spot, and a high spot under a dome means one donut carries the load while the others float. That is the most common cause of a mouse that feels tilted or scratchy after a donut install. Work slowly, remove all old material, and let the base dry completely before applying anything.
Do not use a metal scraper on the mouse base. Plastic tools and isopropyl alcohol on a lint-free cloth are enough for typical PTFE residue. If the base has a textured or painted finish, test the alcohol on an inconspicuous area first.
Install steps for G+ Mini Donuts
- Remove both layers of the stock feet: Corepad explicitly warns to remove both layers of the stock feet before applying their skates. Many mice ship with a PTFE foot on top of a foam or adhesive layer, and people often stop after the first layer. Checkpoint: run a fingernail across the base. If you feel any raised patch, keep removing until the surface is flat.
- Clean and dry the base: Wipe the base with isopropyl alcohol on a lint-free cloth and let it evaporate fully. Adhesive residue left behind creates the high spots that make a donut install feel uneven. Mistake to avoid: applying donuts while the surface is still damp or tacky from cleaner.
- Choose your thickness and dry-fit the layout: Decide between 1.00mm and 0.85mm before peeling any backing. Place the donuts unpeeled around the sensor and balance the load: typically two at the front and two at the rear, spread as wide as the base allows. Checkpoint: no donut should overlap a screw hole, the sensor opening, or the edge of the base.
- Peel and press each donut firmly: Apply one donut at a time, pressing straight down for a few seconds so the PORON foam makes full contact. Do not slide or reposition after contact, because that stretches the foam and weakens the bond. Mistake to avoid: pressing only the PTFE cap while the foam edge stays lifted.
- Test glide on your actual pad: Put the mouse down on the pad you play on and make slow circles and short stops. On glass, the domes should feel defined rather than floaty. On fabric, expect a slightly slower, more planted feel. If tracking is inconsistent or the base scrapes, switch to the other thickness rather than adding more donuts.
- Let the adhesive settle before judging: Give the foam time to fully bond before a long session. If a donut shifts after a few hours, remove it, clean the spot again, and reapply with a fresh piece. Next step: keep the spare donuts from the set for future re-dos, since universal placement means you may want to adjust the layout later.
Product facts behind these recommendations
- Corepad Skatez G+ - ONYX Universal Mini Donuts (1.00mm / 0.85mm thick): Corepad Skatez G+ ONYX Universal Mini Donuts are available in 1.00mm and 0.85mm thickness, use black refined PTFE, and are recommended for glass mousepads while also being suitable for fabric pads. This is the core of the thickness decision: both sizes share the same material and dome shape, so you are choosing clearance and feel, not durability or glide class.
- Corepad Skatez G+ - ONYX Universal Mini Donuts (1.00mm / 0.85mm thick): The G+ designation means a special dome shape: convex and curved outward, optimized for glass mousepads. PLUS refers to the PORON foam layer. The dome and foam are what separate these from flat universal dots, and they explain why the recommended use case is glass rather than cloth.
- Corepad Skatez CTRL - Razer Viper V2 Pro: Corepad Skatez CTRL are made with a special heat treatment process that creates an evenly smooth surface, making them more controllable and slightly slower than the regular PRO series. Useful as a reference point: if you already know you want a slower, more controlled glide and a pre-cut fit exists for your mouse, CTRL is the more direct route than tuning universal donuts.
- Corepad Skatez - Razer Cobra Wireless: Corepad Skatez for the Razer Cobra Wireless come as one pack containing two sets of skates at 0.80mm thickness and are made of 100% pure PTFE. Shows the alternative when a pre-cut set exists: two full sets in the box and a fixed 0.80mm height, with no placement or thickness decisions to make.
