I have used George since I started...way back in the day of late '06
...and to date I would say it is the single best 50 notes I have ever spent on my business...
Could it have more bells and whistles..yes...but then again it is a great program, does what it needs to.
I have tried various other window cleaner programs and found them to be either 'not ready' or too basic...I think George covers this middle ground very well indeed.
But as with all things...it's just my opinion and other will have theirs.
Cheers
Dave.
