I had a professional install them for me. The brackets are sturdy but save your time and do not buy the white ones. Assembly was easy, even with broken wrists! Comodissime! The was great for her chubby feet. Ive tried several coolers that plug in via USB and blow out air. The JLab had really good reviews at a decent price, so perfect for what we wanted. But for an everyday mouse, this thing is quite phenomenal and I would reccomend to anyone. Do not use the headband too tight to your head, it can get very unconfortable up there. They use to make some tan ones with a red sole and I got a ton of compliments every time I wore them.
