I like that you can do text searches, as well as image metadata (EXIF / IPTC) - both very helpful when working with images online! The price makes it difficult sometimes if your budget is tight/limited but this comes down not only because they have an excellent product at their fingertips though also more so than anything else just how useful all there products are!! There's nothing i dislike about tellfinder except maybe perhaps some minor issues here &there.
It works amazingly. We've used many different tools over our careers-and while these days most things work pretty fine we still need something specific now&then where a simple google would suffice before..
