Good value, straps nice, the brackets are a bit small
Overall for the money this is worth it just for the straps with the innenr brackets being a potential nice thing if they fit for you.  They are too small for me to really utilize them long term and provide truthful feedback.<br /><br />However for the straps, these can be game changers if you have to wear a mask for long durations of time.  I have grown dependent on these little guys as we just welcomed tiny twins into the world and they are remaining in the hospital's NICU for several weeks.  I'm up there several times per day for several hours and ALWAYS use one of these extenders.  I could wear my mask without the need for this but it is a huge help in keeping me comfortable without and fatigue or soreness on my ears from the bands.  I'm not sure how much of an extension it offers if you truly need that capability since I'm always on the outer most prongs.  But these are a huge help for me!<br /><br />I've seen a few different types of designs for mask extenders.  They seem to work well for me personally.  I saw and tried others that are thinner and more like a 3D-printed plastic than a rubbery silicone material - with mixed reviews and perhaps 1 important variable for me is that I have a shaved head.  So these don't mess with my hair and they happen to hold well at least for the few masks I've used them with.<br /><br />I use these only on occasion as I have a few masks which I like but the ear loops are not stretchy and this don't all fit me well unless using one of these extenders.<br /><br />I'd say that I would recommend these if you have some masks which you'd like to use but just don't fit well due to ear hoop restrictions.  Otherwise I don't see much of a point other than taking avoiding a mask tugging on the back of your ears if you need to wear one for hours.
