I love this tool. Works just as well as a corded bulldog but there is no problem with the cord. I use this daily in high rise construction and it's great. Helps me to work much faster and more efficiently. I would definitely recommend it to anyone considering it, especially if you already have Makita batteries. I've definitely tested it and it still works just as well as the day I bought it. However, if it breaks, I will not hesitate to buy another one.
