Moving to these flashes from Canon's own brands, I have been very impressed.
The Li-ion batteries last far longer than standard AA batteries and offer better re-charge times.
Apart from a few very small niggles, including the time to first charge after switching on, flimsy reflector, and lack of water-resistance, these flashes are now a part of my daily kit.
The ability to adjust output individually from camera is a great bonus when using off-camera flash, and the simplicity of the controls makes them easy to use.

New oven bulb
Easy to install and does the job exactly as required. Not a lot to say about a bulb, but it does the job.

An amazing lens
This lens does not disappoint in the slightest. Good focusing and very sharp images. Great focal length range on a full-frame sensor, and would give even better reach on a crop sensor. Loving it.
