One big problem for me ....

"I loved these refills, and had great fun setting up my portfolio of digital music ... but then came a HUGE problem I had not foreseen! I was actually using some of the sheets in a performance, because I hadnt yet memorized the music. I had them right in the portfolio, ready to go, but I found that out TOO LATE that the sheets are not anti-glare!! I could not read the music because of the glare from the lights behind me! This was awful. I had to quickly take them out of the sheet covers in front of everyone. Most embarrassing. I cant buy more till anti-glare ones are offered. Ill have to use regular notebooks and sheet covers. "
