I have tried a number of blowers, especially as crammed camera bags make it tempting to find a small one which can do the job equally well but the fact is, they don't! My personal compromise was to cut off the fins (sorry, design team) which makes it quite a bit easier to fit in and obviously doesn't affect performance. Despite the advice given as to it not being recommended for sensors (understandable lawyer input) I happily use it to clean superficial dust off the sensors of my (expensive) camera bodies but of course you must do it without putting the nozzle inside the body. Despite moderate abuse (squashing it in bags, sometimes with the nozzle bent slightly to one side) mine has been in use for over 5 years. Impressive.
