- Joe D.Works as promised! Time saver!I'm one of those dudes that keeps strands of Christmas lights year after year, spending/wasting too many hours trying to resurrect old strands for "one more season." Many folks simply buy new every year and avoid the frustration (and finger pain) of swapping bulbs out until the strand finally works. I skeptical this product would do anything other than waste more of my time . . . I was wrong. Although the unit feels somewhat cheap, it functions as promised. Have a strand of lights with only half the bulbs lit? Unplug a bulb on the "dead" half, plug the socket into the the Light Keeper Pro, pull the trigger a few times, and the darn thing springs to life. This didn't work on every dead strand, but it did on most. Those that didn't respond went straight to the trash bin. That in itself saved me a ton of time compared to prior years. Another feature I didn't think I needed but am glad to have . . . a light bulb tester. I have tons of old bulbs in a Ziploc bag to use as replacements when fixing old strands at the start of the season. Many of these don't work and I used to keep swapping bulbs until one lit up. With this device, you can test the bulb before inserting it. Dead bulb goes straight to trash. Another time saver. In addition, this has a bulb remover device, sorta/kinda like a bottle opener for mini lights. It's finicky but functional. Saves the sore finger problem I usually expect after pulling and replacing so many bulbs. Maybe the biggest bang for this device is the ability to use it AFTER the tree is decorated. If a once functional strand goes dead, simply hook it up, pull the trigger, and you're back in business!
I spent a few hours today using the Light KeeperPro. By the end of the process, I was really glad I bought one. I would certainly purchase this again. - Amy FarlowThis product works, saves time and moneyThis thing really works! Fixed 7 strands of snowflake lights that aren't available anymore, some weren't lighting at all. Fixed a pre-lit tree and and a few strands wound in garland. Basically a lot of lights that would have been really difficult to track the problem on. A few clicks on the trigger and they lit up. Great product!
- Scott HildrethAlmost, almost perfect & still worth the cost even if it can't fix every string of lights you have.This worked, in almost every case, to immediately fix a string of 100 incandescent mini-lights where one or more 50-light portions would not light up. Its handy bulb tester was great, and the bulb-puller also quite useful. The audible voltage indicator worked for *some* strings of lights to find a suspect bulb, but would not ID failing bulbs or bad sockets or wires in every case. (It seemed to have the hardest time with tightly wound 3-wire sets, constantly providing the rapid detection tones at every bulb even if that section would not work.)
There are numerous helpful videos available to show how the LightKeeper Pro operates, and indeed it does work just as shown. The instructions are clear, and the tool is safe to operate if you follow those instructions.
For the price, this is still a lovely little tool, and if you still have numerous and various strings of mini incandescent lights as we do, and you struggle annually to identify the bad bulbs, as I do, and you swear a lot when trying to figure out why some strings no longer light up, as I do, it is more than worth the cost. True, it might not fix every string. And yes, you *can* buy multiple sets of new lights for less than the cost of the Lightkeeper pro, and save time. But if you don't want to throw things away, and you refuse to let a string of lights beat you (especially as a retired electrical engineer!), and you want that neat feeling of having fixed something, then this is indeed the tool for you. - Jim CrapanzanoSave your money!I saw the commercial, I watched the You-Tube Videos, I thought AWSOME! So I bought it looking forward to all the benefits it claims. However, I can sum this product up in one word: USELESS!
The first thing you need to know is that it will NOT work with light sets that have a programming box for multiple blinking options. --why did I have to buy it to find that out? It's only mentioned buried in the instructional tri-fold.
The primary reason I bought the thing is to repair the programmable $18.00-$24.00 light sets, who cares about the standard 150 light sets that can be had for $3.99 in any dollar store? But guess what? It DOES NOT WORK on those either!
Yes, I followed the instructions; I read, and reread, them; I watched several videos, I wasted about 7 hours and $18.00.
They claim that the number one cause of failure is a bad shunt, and the click method is supposed to fix that most of the time. Well, apparently none of the 6 strings I used it on had this problem, or the click to fix dealie don't work--take your pick, I still can't figure it out. Then I used the sound troubleshooting method. First, it's very inconsistent as on one pass, it stops beeping, on the next pass over the same spot it beeps--and yes, again, I was following the instructions by the numbers, So when I think this is probably the problem bulb, I pull it and test it, the bulb was fine. Using a magnifier and adequate light, I confirmed the socket was just fine. So it told me nothing. Finally, I reverted to the old fashioned way-- replacing each bulb one at a time. Meanwhile, I kept using he light keeper as I went, hoping to see how it acted when the actual problem was manually found. And guess what, it falsely indicated no problem at the bad bulb! (The tester was beeping away, indicating no-problem there!) So, finally I found the bad bulb and fixed it, but no thanks to the Light Keeper Pro. The only reason I kept working on that cheap set for almost an hour was a dogged determination to figure out what I was doing wrong. I mean it worked in all the company and user videos, so it musta' been me right?
Pig-headed, never say-die, guy that I am, and again, just in case I'm missing something, I went to work on another set with one of three sections out. Same process same result! Then on a another set that I couldn't fix at all. Bottom line, either mine is defective, or the product only works for a very specific malfunction which, apparently, none of my 6 malfunctioning sets had.
If I hadn't seen their commercial, I would have just tossed the errant sets and bought new. What bothers me most isn't the money spent--I'll get that back--It's the time completely wasted watching Videos, reading instructions, and trying to figure what I must have been doing wrong! I have no doubt that I had nothing to do with this gimmicks failure to produce the results promised. Save your money, and more importantly save your time and aggravation!
