Quality:
been using them for a year now and they still work and havent broken.

Value:
i give it a 10 for value cause it was only 5 dollars and as a gigging musician i like to put on a show so if it looks like i have screws in my ears it makes people talk.

Desirability:
i give it a 5 for want because its really up in the air. if you want the funky look of the screw go for it but as far as the quality its a hearo company product and the standars 30 rated plugs work just as well just with out the screw hanging out.

Ease of Use:
just push in a little then screw it a little deeper and you have a perfect fit and a little twist here and there gives you a more adjustable fit.

Support:
dont know if theres any support for this but it was a 5 dollar investment that has let me down just yet

Overall:
I have to give it a 10 they just looked so perfect for my style and surprisingly the little screw ends(made of plastic) serve sort of a dual purpose by making the plugs a little more adjustable in the ear if you want them further in or out for how much you want to hear.
