No Jamo, I have an old 'Jerry' built which is sitting in a corner.
I do see a place for these, travel, weekend away etc where no power or generator. Looking at it it probably would have been a better option than the one I have to learn the ropes at a low cost. Even with all the faffing around I've had to do I still want to do it. This unit might have made the learning curve more pleasurable tho.
Draw backs? Maybe wearing a track in the cards but there's nothing stopping a new starting point for the sweep. Don't know the life span but the cards are reasonable for a set of 5.
The addition of 80 index, the Batt card and dop sets is a bonus now. Size of stone ability I haven't a clue. Wearing of the feet, no idea.
If I WAS to add something to this it would be a larger transfer jig and maybe a spare dig.angle meter oh..and maybe dops for bigger stones if it's doable.
Would be good to get feed back from those using it. Not knowing its physical size raises the question of technique, eg. I like to have my fingers on the stone when sweeping on mast style, is it possible with this? Is one hand holding the card and the other is needed to move the unit from the back end or is the card fixed , use the left to hold the stone while sweeping with the right?
At least if you HAD to finish a stone and there was a power outage you could still get it done.
I've seen some with a superb finish, some look like they've tried to polish scratches out. You still need to take the same care removing scratches through the stages.
Notice the grits jump from 250 to 1200, if it was me I'd probably get a 600 happening before the 1200 and depending on amount of removal and the material, not using the 250. It'll be the same process, what works best, trial and error as it is with using a power unit.
Also with the Batt card now, maybe you can still go from 600 to 3k on the Batt then final polish.
Apparently years back a chap made the Laplap and would use it during air travel to pass the time. Don't reckon you'd be allowed to do this now.
