Full research notes and sources

What it is

The Corsair MM300 PRO is a cloth pad offered in Medium (360 × 300 mm) and Extended (930 × 300 mm), both 3 mm thick. Corsair’s copy describes a spill-resistant, stain-resistant coating that makes liquids slide off and the surface easy to wipe clean, 360-degree anti-fray precision stitching, an ultra-fast glide-enhanced micro-weave textile surface, and an anti-skid textured rubber base. Package contents are the pad and a warranty leaflet.

Spill resistance and upkeep

Corsair’s on-page comparison table lists the MM300 PRO as cloth, stitched, 3 mm thick, Medium and Extended sizes, spill-proof, while the MM100, MM200 and MM350 (non-PRO) pads lack spill proofing. The coating is the main difference. The pages read give no cleaning-agent, washing, or descaling instructions, and no data on how the coating ages. Spill-resistant coatings on cloth pads can degrade with harsh cleaners, so gentle wiping is the safe default until Corsair publishes care guidance.

Fit and sizing

Both sizes are sold under the same “MM300 PRO” name with different SKUs (CH-9413631-WW Medium, CH-9413641-WW Extended). Measure your desk and mouse travel before ordering, since the Extended at 930 mm covers a full desk width while the Medium at 360 mm suits a smaller setup. Corsair lists the Extended at $29.99 and the Medium at $16.99 (regular $24.99) on corsair.com, with 60-day risk-free returns listed on the product pages. There are no consumables; ownership cost is the pad itself plus a replacement when it wears out.
