I don't have much to say, it does what it seems from the pictures. The controllers attach immediately to the base (if you align the mini HDMI of the controller with the bottom part of the base that has a small bump), the batteries charge in a normal time, neither too slow nor quick charge, they are 1100mAh and I will also edit when I try to empty one, to see how long it will last. It is sleek without intense lights etc. apart from an indicator for each controller on top, which shows red while charging and green when they reach full. The good thing is that if the battery runs out on one, you can take the other from the base and continue. And if you play with 2 people, you can use 2 AA batteries if needed and continue.

Edit: I tried from 100% to 0% and it lasted for 3 days with about 4 hours of gaming per day (so around 12 hours total) and about 2 hours of standby while I left it until it turned off by itself.

Edit 2: I don't see any significant decrease in battery health 6 months later. Each controller lasts for 3-6 days depending on usage, but you can always put it on the base whenever you're not playing, so you never run out. Overall, a very reliable purchase, worth it completely
