The Light Keeper PRO is a fantastic tool. I have an artifical tree with over 1500 incandescent lamps. Every and I mean every year, I have to replace 20-30 lamps that failed due to moving into and out of storage each season. With this tool it literally took under 15 minutes to find these lamps, whereas I have spend up to four hours to do the same task in the past. This is the first time ever I have reviewed a product on line - and I sought out the opportunity solely because how thrilled I am with this tool.

Ulta Lits LightKeeper - hands down! - is a fantastic product!! This device has literally saved me countless strings of lights [and money] where I would have otherwise tossed or been burdened with the time replacing the strings once they were on our tree or outside. Highly recommended!!!!

I have worked this thing for 1 and a half hours and all it is good for is testing bulbs...........it beeps over almost every bulb. Clicking it 30 times while plugged into a socket does NO good! What a waste of money!!

Light Keeper PRO works as advertised. An excellent multi-tool with everything you need to repair lights or lit artificial trees.
