AF speed and optical quality are absolutely fantastic: the same as without the converter: what more can you ask for?
Only 1 stop of light is lost so handholding is still possible with a 70-200 f2.8 or 80-200 f2.8 or smaller lenses.
The teleconverter is very small: less than an inch long so the setup does not get much longer and is not likely to strain the camera and lens mounts.
Can be bought for a very good price second hand: a fraction of what the lenses it works with will set you back.
A 70-200mm f2.8 with this converter is less than half the price and half the weight of a 300mm f2.8!
It's very much a professional quality product.

Expense: very very expensive to buy new. Buy it secondhand.
Not compatible with AF-D lenses. This will not work with the excellent Nikon 80-200mm f2.8 AF-D lenses. Therefore I only have two lenses I can use this converter on, both of them very expensive AF-S optics.
Not compatible with the 28-80 f2.8 or 17-30 f2.8 AF-S lenses or the DX AF-S lenses but would you ever want it for these?

Firstly, I have the newer version: the TC-14E II. This is a simply excellent teleconverter, as is reflected by its very high new cost price of up to £400. I bought it bundled with my mint condition 70-200mm f2.8 AF-S VR lens for £1080 UK pounds for both so I guess I paid about £200 UK pounds for the converter which is about $380 US at the moment.

I see no degradation in the image quality or focus speed of my images when compared to not using the teleconverter, and the teleconverter often stays on my 70-200mm f2.8 AF-S VR lens all day. The autofocus works perfectly with the converter as does the VR system.

I have no complaints to make when put with the 70-200mm lens although I doubt I'd have paid £325 to £400 for the converter new!

It's not compatible with the 28-80 f2.8 or 17-30 f2.8 AF-S lenses or the DX AF-S lenses but would you ever want it for these more wide angle lenses? More annoyingly it won't work with AF-D lenses (it won't physically fit and to try to fit them together will cause damage) so forget using any AF-D telephotos: it's the newer AF-S or the older AF-I only.

So, do your research regarding compatibility before you buy this converter. If you have one or two AF-S or AF-I telephotos that it's compatible with then it won't let you down.

Tack sharp images, used on 80-200 f2.8, 300 f4, 400 f2.8 Small in size, especially compared to the 2x.

The price. But I suppose quality is not cheap.

Been using the TC14E for over a year now and find it just fabulous. When using it with f2.8 AFS lenses I have noticed only a very small decrease in focus speed. On a f4 you can notice a little more slowing of the AF but on both occassions its tack sharp and focusing is direct with no hunting. Must admit I never worry about picture quality as its just as good as the lens you are using. Only one stop loss is great appeal

TC201 other converters. Never happy with anything but a Nikon for quality

rather short; thus making the overall length of camera-converter-lens not significantly longer. -> no big danger of breaking.

covers are difficult to stick on when changing in rush (e.g. shaking airplane, train)

A nice converter to carry with as it is not too heavy and small in size. Actually, I planned to head for the 2x, but one aperture to loose with the 1.4x is enough.
