Gardner Bender Sperry Instruments CT6101 Heavy Duty Continuity Tester, 2 Range, 36 inch lead, Yellow

I agree with some of the reviews that mentioned a little difficulty pulling out the cardboard tab inside the battery compartment, or having to search for the proper battery orientation (it's on the side of the tester itself), or that the bulb fell out when the battery cap was unscrewed. All true. And yet I'm giving this device five stars because 1) it cost less than $6.00 and 2) it did the job! After a bulb blew in a table lamp, I noticed the socket was discolored. Given the lamp is 20+ years old I decided to just replace the socket. Thanks to youtube for the easy instructions but there's always the thought that you reversed the polarity or that there might be a short. Not being familiar with using a multimeter, I just wanted a simple continuity tester and this one fit the bill. Once I had the batteries installed properly. I was able to check that the batteries were good, verify that the polarity was correct, and that there was no short. For a very small investment I was able to confirm that the job was done properly, and to start using my lamp again. For those unhappy with the quality of the tester, there are more expensive options (including a range of multimeters) that they'd probably be happier with. But for a simple, inexpensive device that easily checks continuity only, getting this tester is a no-brainer.

Good continuity tester bright enough except for direct sunlight easy to use

This looks like it should hold up. I'm knocking off a star because of two reasons. The battery access cover was screwed in very tight. I had to use pliers and had to use enough clamping pressure to almost damage the screw in cover. Once the cover was off, I saw the cardboard piece that has to be removed, but it was collapsed and stuck about 2 inches from the opening. Fortunately, I had a pair of small forceps and managed to remove it.

Great item,fast ship

I have owned a continuity tester for decades, but I have never needed it. This week I needed it, and when I assembled it and put in the batteries the test light turned on and stayed on like it was a flashlight without an off switch. Not good for a continuity tester. I went to my local big box hardware and building materials store, and all they had available was electric multitesters for four times the price of this instrument and it would take time to learn how to use it. So I ordered this one. I read a lot of reviews that were critical of this instrument, and I appreciate the fact that they told me what to do if it had been wrongly assembled. But when my instrument came today, a full day sooner than it was promised, it was easy to load up and use. It is a terrific value at this price. I knew how to use it as soon as I got the batteries loaded. It was beautifully packaged in clear stiff plastic, but you could slice your hand open if you opened this packaging in a way that permitted it to cut you. I used heavy duty metal snips and worked slowly. Even this difficult packaging is an advantage. I bought my non-working continuity tester at a going out of business sale at an old fashioned hardware store. It was packaged in a soft see through plastic sleeve with a zip lock opener. I think someone was missing a part from their tester and took a part that I needed to make mine work. I don't like the modern packaging in hard plastic, but that makes it impossible for someone to remove a vital part without showing a lot of evidence on the packaging. My thanks to Amazon for very quick service, and for also publishing critical reviews so that I would have known what to do if my instrument had been wrongly assembled.

I was looking for a simple, quick continuity tester. I would have paid more, but this was supposed to be just a simple, single function instrument. Nothing more, no great expectations -except it work properly.Well, I looked at the instructions for inserting batteries, and the orientation is on the case, so that's a no braver. So, I inserted the batteries and as I screwed in the battery compartment, it pushed the bulb portion off the instrument - bulb and spring fell out. So, I got out the super glue, glued the tips piece back on permanently, and reassembled the unit. Put the batteries in, screwed in the base as designed, and did a couple of tests. Shook it a little, beat on it a little, and it still seems to be working. So, while I had to "fix" their mistake, I suppose you get what you pay for.For God's sake in 2021 can't you make a simple instrument that is or assembles correctly. Also, please use an LED light, so it will last a lifetime and be more able to take a beating (no filament to break).I have a perfectly great multimeter, so I can easily do continuity with it. Please make a decent product!Peace.

Todo bien seguro
