Yes. They do suck.
I am not suggesting that they are performance worthy at all. The number one thing that I HATE is missing my daily practice session. I see practice mutes not as a tool necessarily, but a necessary evil. I have to admit that I sound like S**T when I use one, but at least I get my workout in whether it be while the baby is snoozing, or I am at work during my prep period, or in a hotel, or where ever.
