Utter waste of money. Full stop.
All it is, is Unger trying to find a way to get you to buy something new that does exactly the same as the old by making it look a bit more flashy and using the 'in' term 'aircarft grade aliminum'. We're talking about a 10" or 12" or 14" etc bit of metal that doesn't suffer high degrees of stress not something at the edge of endurance.
Plus, if you buy the squegee, you have buy the ninja bucket thingy as the squeegee won't go in any other Unger boab. Not only that, it has the word 'ninja' written down the side in big white letters. What has 'NINJA' got to do with window cleaning? What are we, 1st dan window cleaning?
Also, it doesn't seem to fit properly in the boab and is arkward to use when using the 'ninja' boab anyway.
For me, it was a lesson in how to waste money and look a right pillock at the same time.
I've gone back to using the ergo tech stuff I used before I wasted hard earned dosh on believing the hype.
Quicker and better, nope. Not at all. More efficient and all that, you've got to be kidding. It's a squeegee and nothing else.
