I have to recommend this product.
It clamps down to nearly 0. i can hold pens in it if i want and it holds hobby bits with absolute ease.
RPM is 0 to 600 so it actually drills through the plastic as opposed to my Dremel which only goes from 5,000 - 35,000 RPM and melts the plastic even at its lowest setting.
The charge seems to last just about forever.
And even though its only 12v it has enough torque to used as a screw driver and ratchet.
For only $30 dollars its a great deal.
I've been very pleased with it.
