Does a great job at redistributing the weight so you feel less torque on your head/neck; pads are nice and soft as well. It doesn't slide around the headband, it's going to stay right where you put it. Charging the batteries via a standard USB-C is amazing, as I don't have to figure out which battery charger to get (and power source). LEDs on the case show the charge level, allowing you to see with a glance how charged you are. Haven't made use of the micro SD-card slot myself yet, but I appreciate the option.

Works perfectly -- I can't imagine using my goggles without this, tbh. Also glad to see they're working on a (free) updated part to add some cable strain relief, too!

Battery pack itself works fine. It has a defect with the power cable coming out of the pack that causes it to not work after a while. While the company is proactive with providing 3D prints that help prevent this issue, and they say they are coming out with a permanent solution, I’m really hoping that they provide the solution for free without shipping costs. I understand that no product is perfect, but at this price point I shouldn’t pay a cent more due to an under engineered product that didn’t go through enough testing. Otherwise it’s 5 stars.
