It's a good script but it could be better. I wouldn't trust it unattended and i wouldn't let it run too long. It keeps attempting to cast even if you've run out of runes or items to alch. It cast high alch on the item without ever switching to the inventory. If you're ever near someone doing this, you're easily identified as using a bot. It would be nice if they had a world swap feature. But it's free and it fills a niche that no other script does.
