The bigger battery makes all the difference
I purchased a similar item in the past and it certainly worked adequately. But, the earlier models had smaller battery capacity and could barely make it through two feet worth of sanding. This new model has a  1200mAh large capacity lithium battery. That is what makes for a significant improvement from the older one. I have yet to come close to running out of power.  More power equals more effective, consistent sanding. I do like the other new feature also, which is the headlight. it's a little silly and gratuitous, but fun to see the little flecks flying off in addition to the little coating of skin dust. TMI, I know.<br />Anyway, compared to the older model, I'm quite pleased with this purchase.
