My advice - do not buy this product unless you are willing to throw it away if a part breaks down.I have used my Yardstick trimmer for a number of years and have no complaints other than the batteries didn't last as long as I thought they should. My problem arose when I tried to order replacement batteries. I placed the order over two months ago; my credit card was charge soon thereafter for the purchase amount. I placed a follow-up call before paying my credit card bill. I was told the batteries were back-ordered, but I would get them within a week after May 5. I paid the credit charge. After an additional five (5) follow-up calls, I still have not recieved the batteries. So, buyer beware!
