  1. So after reading your review which states it has a 120v battery and checking out the specs on your amazon link I find that it is not portable battery powered driver but a corded one.
    You may want to make that correction in your review specs.
    Otherwise, it’s a Bosch tool and, if you’ve got 120v power available, it’s a great product.
