Waited a bit longer but this came in from the USA and was cheaper than buying it in the UK. The nozzle stays put and there is plenty of puff for cleaning the sensor. They are quite big but work really well. Good product and well made would recommend it.
Excellent piece of kit, does its job perfectly. Some may find it surprisingly large, but in order to get that much of a puff you have to move a fair amount of air, hence the large bulb size. Would I recommend it to another photographer - whithout hesitation.
I had one of these and lost it in the Lake District. It is invaluable for clearing the lens and/or filters of dust. Best I have found, much more effective than a brush and not a scratchy as a cloth. Hoping the red one will be more obvious to spot if it drops out of my bag!
