Bought the Mad R+, the extra battery life for the slightly heavier weight is worth it. Lasts for over a week per charge and the software is honestly pretty good even if some parts of it are in chinese even when you set it to English.
Bought this off the store on aliexpress since the shipping there is free and it's great value for a really premium feeling mouse (obvious there are some limitations with the super light plastic).
There are better options if you want the lightest and most premium feeling mouse but for this price point, it's a great mouse.
