TechPowerUp published a review on the Pulsar Xlite V2 Mini Wireless
A quote from the article:
As the name already suggests, the Xlite V2 Mini Wireless is a smaller Xlite V2 Wireless. Much like its bigger brother, it comes with PixArt's PAW3370 sensor, Kailh GM 8.0 switches for the main buttons, and up to 70 hours of battery life, all wrapped into a 56 g lightweight package.Pulsar Xlite V2 Mini Wireless Review
