and my king mattress is disgusting. The manual was clear, as it labels and identifies the different parts of the mouse, and then goes into connecting, through various methods. I really hope these last a long time so I dont have to modify this review in the future. The volume of the headset was appropriate and decent had it not been riddled with static. I got these for a Christmas gift and they didnt fit the recipient. It seems pretty durable, I’m not sure it could really handle 300lb but I usually use 50-100lbs anyways and it hold up great. Everything about this product was amazing. Fit perfectly, no delay in gaming, and plenty of line to work with! Its also nice and quick for our gigantic long hair cat. Fairly sturdy, right size for tight laundry closet, stackable.
