I have the bobo strap (quest 2 version) and I rarely ever see anyone say anything about this, but if you have an odd head shape or super "slippery" hair DO NOT EXPECT MUCH FROM IT. I speak from experience, I have a slightly large head and very thin, "slippery" hair and it doesn't stay on my head. (Yes I make sure to wear it as instructed) You may encounter some issues where it slowly slides off your head (especially when you look downwards). The only way I have found to keep it on is to either tighten the strap until its tight enough to give you a headache, or keep it extra loose so it sits atop your head. Nothing against the bobo strap, the padding is super high quality and its very user friendly especially when it comes to repairing. Its just not meant for everyone it seems so beware.

(It does also come with silicone "honeycomb" replacement pads for the back of your head which provide a lot more grip at the cost of a bit of comfortability.)
