I'd agree with Propole.
It's a cracking training aid and I wish it had been around when I first started, which wasn't that long ago (four years).
It would've saved me a lot of grief, tears and made me more cash.
Saying that, it was good to watch and I still learnt at least five good tips; some of which I'm now using everyday and I can think of a local window cleaner (whose been at it for around ten years) who'd benefit greatly from this DVD (not Squeaks; I'm not having a dig at him).
PS.
To Pro,
I also think Mark's cleaning resources website is good, but it's bad forum ettiquette to overtly advertise another site in this, or any other forum.
