Do not buy this product.
Your review: Product arrived on time. Did not power on out of the box. I thought the battery was dead so I bought a replacment battery for 5 bucks form local hardware store. Still did not work. I called customer service and they sent out a replacment which arrived in 2 days. No questions asked. Replacement worked for literally 5 minutes before it started acting unreliable. LCD flashes and unit does not work unless you say an OurFather and a Hail Mary. General Tools should be ashamed to sell this product. I would not recommend this product to anyone. Complete waste of money. Kudos to Global for their Customer Service though.
