I have a box in the cupboard with about 15 squeegees in it of all different types and makes. At the time of buying, all the manufacturers claimed the same as the liquidator as in 'this is the best so far'. Yeah right, sure it is. It's all about getting us to part with money.
I loved trying something new until recently. I now realise that a squeegee is a squeegee. Change the packaging, shape of handle, play around with the channel, use different metals, market it in a different way, and so on, etc, it's still squeegee based on the same principles and it still does the same job.
