Really not happy with the wagtail! Got delivered today and I just can't get used to it, it's jumping around the glass, missing bits, can't get a perfect window at all!!! With my liquidators I'm doing no detailing at all and it's easy work, I'm finding the wagtail is aching my wrist, and just isn't doing a nice job at all? Is it just because I need to get used to it? It's so jumpy, even after changing the rubber, I've also dog eared it and still getting loads of detailing... Really frustrating!!
