User interface could be better - it is quite different compared to today's EOS cameras and a manual is necessary to understand all functions. The AF is pretty lame but still quite precise. Flash system is just soso. Quite a bit outdated by todays standards but probably still worth a thought as a beginner's camera. The batteries kept being exhausted about every 4-5 rolls of film, and the lens wouldn't close it's aperature on time.
Funny thing is, that it still took decent pictures.
The camera reapir shop told me that there were two faults, one being in the circuit board of the 630 body, and the other with the USM mechanism of the lens. Unfortuneately, both were deemed to expensive to repair. The Elan 7, although faster and quieter doesn't seem to compare with the ruggedness of the 630. I must admit, I will miss my 630, but I have lots of great pictures from it. By the way, the 300Ex speedlight works great with this camera.
