Works great. I bought a Fowler test indicator 3 months ago and the needle went weak (which shouldn't happen) so I bought this 1. I paid $30 for this indicator, I paid over $100 for the Fowler indicator. I called Fowler, they told me to fill out a form on their website, which I did. So far there is no news from them, and a month has already passed. Don't waste your money on these expensive ones. This SHARS revolves around Fowler. I RECOMMEND this indicator.
