SteelSeries Aerox 5 - Holey RGB Gaming Mouse - Ultra-lightweight Water Resistant Design - 18K DPI TrueMove Air Optical Sensor

- the mouse depends on an app. that needs to be ran on startup - the app requires sign up and is a combination of 4 or more mini apps including audio related apps that you can choose to disable but will have to remain installed - when you start your computer the mouse will begin cycling through full brightness rainbow colours as its default setting before your custom profile is launched. mouse doesn't retain its settings on actual mouse - the mouse has a ton of settings which is nice. then doesn't allow for sub 100 increment whole numbers when choosing your DPi. I found 1700 slightly too slow. then 1800 a bit fast with no middle ground. but then you can adjust the acceleration and slow down to dial it in. just takes a little more time - the 5 side buttons are great with all the options to set them as anything you would need. although one of the buttons is ergonomically a bit awkward being a paddle button that activates with an upwards click and will literally have you lifting the mouse from the table to use it all in all a decent mouse. worth the price having bought it in the xmas discount period
