This device is a real time saver when you have a lot of sanding jobs. It's not hard, but it's not easy either, and after a while your arms and shoulders will start telling you. All this to say it worked well and did what I needed.The dust hose may need some adjustment as it won't easily fit in a standard vacuum.If you have a decent shop vacuum and your filter element is clean, the dust extraction works pretty well Overall I'm happy with this purchase and it ended up saving me loads of time.
