cv-8f-end: This page is a little confusing and needs more color, pictures and some videos!! The information you have is good, you just should explain it more.
CV-8F-KEA- Could use a lttle more information, the pictures you do have are really good but it could use a few more!

cv-8f-kpi: So this could've used a little more explanation to some things, for example, the cause of the disorder doesn't look like it's in English! hah.. also there could've been like a little more interesting information, like extra "stuff."
cv-8f-ecb: there was some good information on here but the page was a little boring. It was also a little bit confusing
