From the 3 I received today, aside from the loose fit, they work.
In my case it's been realyl difficult to break them in, two have that nasty "metal" taste after blowing them several times. I'm vaping VG to remove that taste.
One seems to have bigger air holes because I can hear the air and the drag is different.
Tip.. I just discovered an amazing trick... Using one of those "blowers" to clean cameras, you can crean them, brak the seal easily. I have a giotto medium, so I'm guessing the bigger one would do a great job! And those are cheap...
