the sham wow of yoga towels?

it was almost comical to stumble upon these thirsty microfiber yoga towels, especially because i have been joking with one of my students, who constantly uses a towel to dry off his mat, to see if a sham wow would effectively save him some time during his constant wipe downs. for only $10.95, it certainly is a cheaper alternative to the $19.95 shammy & the $30 yogitoes hand towel. anyone out there have one already?
