Purchased for use in the house, it has more than paid for itself and has never been unsuccessful. Conveniently small, not overly heavy, and not too difficult to handle. The charge on the battery is holding up really nicely. It has plenty of room inside. Comfortable. It is likely to be of limited utility in the context of private building and the commercial rehabilitation of existing structures. In normal life, a screwdriver is the best tool for the job. It is in your best interest to buy.
