2 Sets of Hyperslides Rounded Curved Edges Mouse Feet, Mouse Skates, Pads for Glorious Model O / O- Wireless Gaming Mouse Feet Replacement (0.8mm, Smooth Glide, Pure PTFE) Pro Performance Upgrade

These skates work: fit well, adhere well, and remove cleanly. The adhesive is 3M 9448A Double Coated Tissue Paper. I measured their full profile height as 0.78 mm new (including the puffed out section described below), and 0.65 mm after 16 hours use on the Glorious Air pad.These skates do not glide as smoothly as Glorious OEM skates (1 for $7), nor other PTFE skates, e.g., Corepads (2 for $10, 0.96 mm height), Tiger Arc (2 for $7), ICE (1 for $8). The center is "puffed" out, leaving an air cavity between the skate and mouse bottom, similar to the construction of Corepad PTFE skates. The shape of the puffed out section leaves a nice long rounded ramp, which might help create smooth glide and smooth direction changes, but it also provides a smaller glide surface, since the entire foot area available is not used to support the mouse, which might contribute to the less smooth gliding experience. Worse, the skate material is very flexible, and the puffed out middle section collapses too easily -- it crushes down -- unlike other stiffer PTFE skates, e.g., Corepads.The low-ish cost (at $8 for 2 sets) is OK for testing out different mousepad surfaces, e.g., hard pads that wear out feet fast -- these skates last about 16 hours on the Glorious Elements Air. Other better quality skates are available at comparable prices (as listed above).Note: The packaging is minimal and not all feet we received survived warehouse storage and shipping well -- one order arrived crushed.

Just buy corepad skatez or real hyperglides. This company is pulling a con making the name so close to hyperglides and nearly tricked me.
