Excellent product, easy to read without glasses, works on every type of battery and does not require any additional power source other than batteries. I use it with a small LED flashlight for all kinds of things including checking my golf swing. The LED is much stronger then the old flashlight. A plus is that I can clip this device anywhere in place which makes clipping or removing your shoes even easier. If you need a great reliable wireless device, get this.
Output:
Good Review
