The Unger Sprayer On A Belt is exactly that, a trigger sprayer that slips onto any belt that has a good length of curly pipe leading to a hand held trigger which also slips into a purpose made holder on the side of the sprayer. I've never felt that the pipe should be longer as it's a curly one and stretches a fair distance but the spray can be altered from a mist to a jet that can be aimed right where you need it up to around 15 feet. It has a 1 litre bottle which is easy to screw off and on in order to refill and it comes with different coloured sticky labels in case you have the need for more than one with different liquids in them. In the case of most window cleaners the need to carry a cleaning solution like Virosol etc is essential and the SOAB makes that so much easier especially for the traditional cleaner as theres no need to climb down your ladder and run off to your vehicle to get it if it's already there on your belt in a convenient sprayer. Personally it's proved invaluable to my own method of cleaning as I try to reduce the amount of water that I use and with the SOAB I just give my applicator or the glass a few squirts which is more than enough for a large window normally but if it's not the water is right there on my belt so theres no need to come back down the ladder to dip my applicator in a bucket. All in all, whichever of the uses above you want it for it does the job and does it well. The SOAB is convenient, easy to use, strong and sturdy. I've been using the same one for approximately 6 months and it shows no signs of the trigger wearing out, the threads on the bottle and belt attachment are still water tight and the belt clip is in one piece with no cracks etc. Because of the method I use to clean this is the best piece of kit that I have ever bought and would recommend it to anyone. Quick edit, I snapped the trigger last week but bought a hairdressers sprayer bottle from a shop near me for £1.00 and the trigger fits perfectly and just screws on like the original, the bottle also fit although is smaller but good to keep for a spare.
