I always struggled to clean the air vents and inside the wells for the window switches etc and typically resorted to blowing into them to clean out the dust.
I got one of these gizmos for the laugh to see what it's all about. Unfortunately they're not widely available, nor did they ship to ireland so I had to ship to the states and have it brought back.
On the actually product though, it's amazing. It blast air at 220mph and really packs a punch, I cleaned all of my air vents, switches, corners and hard to reach areas and I was astounded by the crap it lifted from some places!
Definitely a handy gadget to have as it's more environmentally friendly compared to canned air.
Got mine for around €80 which is expensive enough but I'll use it around the house too!
