I have the same question may even be the same unit, I've viewed a
similar unit from Harbor Freight [ http://tinyurl.com/6m7b7 ] I've also
seen other photos of possibly the same unit from $30.00 to $80.00
My question is - exactly what are these types of units capable
of? How long will they last? Would they be strong enough to remove
polishing compounds? Finally, and most importantly - what is the
catch? Even the small, standard ultrasonics that have squared
metal casing are far more expensive than this... how can this unit
be so cheap?
My suspicion is that, yes, it's plastic and certainly no rugged
unit. I suspect the price is more a result of mass and/or 3rd world
production and large scale distribution. I too would like to know if
any of this noble crew have experienced this little guy, for use in
a limited budget start-up mini-studio.
Thanks to all,
