Groov-e Air Duster Can - Compressed Air Cleaner for PC, Canned Air Spray, Can Dust Cleaner for Keyboards and Electronics - Extension Straw, 400ml

Does the job. Quite noisy but that's to be expected. Be careful and read the instructions, I instinctively shook it before reading the "Do not shake" warning.

Bought to clear car washer bottle and jets. Did the job very well

I have used it for cleaning the internals of an old MacBook Pro and it was great, as well as a keyboard.Keep upright or the liquid inside will spill out, it does evaporate off quickly.Also remember to not shake it as that might increase change of spilling out and make sure any electronic devices are cool before use.You don’t want to set your device on fire!If using the nozzle for tighter spaces make sure it is in firmly, I found that putting it in an angle then forcing it in helps but it still falls out.Value for money it is great and has lasted well.

Good for cleaning my PC of dust in otherwise unreachable spots

It worked fine at first, but after a few seconds the pressure drop and it became more of a breeze than a gust.

Excellent

Good product

As mentioned by numerous others, the nozzle does not fit at all. There is no attachment device as in the pictures, just a plastic straw that it too big for the spray hole. It'd be quicker to just flush four quid down the toilet.
