One of the most common visible signs that you're experiencing extraction issues is through channeling (or spurting), which cannot be seen with a standard spouted portafilter. Exposing the bottom of your portafilter basket will allow you to witness these extraction issues first hand, providing an opportunity to diagnose and improve the quality of your shots.
PLEASE NOTE:
Channeling and spurting can be very messy, but these are very very common. This is not a defect of the portafilter itself, but instead is your coffee telling you that there's room for improvement in your preparation process (grind size, tamping, distribution, etc.)
