I really missed the Endotec II thermal compaction device, until I received the Root Buddy. I love this thing! When I use the heat mode I get as much extra gutta-percha compaction as when I used the Endotec II, but when I use the vibratory mode I get even further down the canal and can significantly more material. The gutta percha just seems to flow and fill the tooth remarkably better. This is a far better system to others I have tried. Root Buddy is the system to use.
