To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Perfect for my Rift S Touch Controllers, I have been using the AA batteries for about 4 hours of use and they're still at 50% charge for the right controller and 80% for the left controller (makes sense since I'm right-handed lol) and I mostly play beat saber which on almost every official and custom map has more blocks on the right than the left, would recommend if you want to help the environment and also save money by not needing to buy disposables all the time, I used to use disposable ones but the average time the batteries lasted before going flat was about 1-1.5hrs depending on what I did and at this rate of using them I won't need to worry about charging them until about 8 hours of use until I should charge them which is great! I might get some AAA's for my wireless keyboard so I don't have to keep using disposables.
