how did i adjust the overflow pipe ? mine is overflowing and i carnt fit a flush master valve [no room}

The overflow is part of the installed system. You don't need your normal overflow pipe - you can throw it away. The overflow works through the plumbing you have just fitted. Try unscrewing the over flow tube supplied - I found that it was too high and had the problem you describe - then adjust the float ball (if necessary) to make sure the level of the water does not reach the height of the opening in the in-built system.

Anybody know how this unit compares to the Torbeck Variflush?

Both units are from very good manufactures we sell more of the Torbeck Variflush but that doesn't mean its a better product.Kind regards,Jo.

how to change batteries

There are no batteries it works by siphon alone.

Is this a complete system? I can't see a ballcock in the image.

No it's not a complete system. IT is only the flush mechanism. You don't need to change the float if it's OK. I fyou have a close-coupled toilet, this requires you to remove the cistern and I recommend you take the opportunity to replace the close coupling kit.
