UPDATE: After further testing, we have determined that SAPPHIRESKATES Type 2 to not be compatible with Logitech G-Series. For our standard shape models (such as Ruby and Blue), refer to the information below.
Some of the most popular gaming mice on the market are Logitech's G Pro Wireless (GPW) and G Pro X Superlight. When conducting product development for Sapphireskates, we thought specifically about these gaming mice when determining the diameter of the mouse skates.
The Logitech G Pro Wireless and Superlight have a unique recessed rear-channel. The thinness of this rear channel prevents gamers from being able to place larger-diameter skates, such as Lexip, within this area.
Sapphireskates have a 7mm diameter which is designed for a snug and secure fit within this channel.
Due to natural manufacturing differences between pieces of Sapphireskates, there's a chance that you may have trouble fitting them here (Sapphire cannot be cast in a mold and is therefore not mass-produced in the same way as PTFE skates, glass skates, and ceramic mouse feet).
However, there's no need to worry as you can most likely get an ideal fit following these instructions (in case you followed this guide and still have trouble, please email ken@sapphireskates.com).
How to Securely Fit Sapphireskates in the Logitech G Pro Wireless and G Pro X Superlight's Rear Channel
In the image below where the green arrow is pointing, this is where we will be placing the mouse skate.


Gripping the mouse with your non-dominant hand, use the thumb of your dominant hand to apply downward and horizontal pressure towards the side wall that the skate is touching. This will cause the side wall to flex a bit, just enough to fit in the Sapphireskate.
Here's what it looks like with 3 Sapphireskates installed in the rear channel:
The benefit of all this is that the mouse skates are held firmly in place which will provide a better overall experience.
A quick word of caution: don't go overboard trying to forcibly-push in a piece that you think may have a potential defect. If you encounter this, please reach out to ken@sapphireskates.com.
