| Support quality | No usable support evidence | Users report uncorrected errors, no channel |
| Public sentiment | Researchers value the content depth, but Reddit sentiment on paywalls and the site experience is heavily negative.⁶ | Users love the free, comprehensive search but repeatedly warn against relying on it alone for rigorous reviews.15 |
| Biggest gotcha | No institutional access? Each full-text article runs ~$40. Never buy casually.⁵ | Searches are not reproducible or comprehensive enough for systematic reviews alone. |
