I've read mixed reviews about this teleconverter and now a newer model is available. I can tell you that I will keep this TC-20E II. I am happy with the results when using this device with my D700 and my 70-200 F2.8 VRII lens. I only use it in good light, but when I need a 400mm range this little lens comes in handy. I rarely need that range, so buying a $6,000 Nikon 200-400 zoom won't work! So far I'm happy with the TC-20E II.
