I'm no expert,but,looks like a real light built model. It takes nothing to get a half or quarter bucket full of pee gravel.with a better built machine you can grab a full bucket of stone & not phase the pump,or move the machine around.
It looks like it would never cut the mustard in a dirt dig situation.
But then again,you can buy two or three of them for the price of one good one.
Guess the feed back will be filtering in soon.
Some pics of the guts,mil per min,bar & weight would be a nice thing to know before spending $2700.
Just my .02.
