Performs on par with tools way ahead of it in price.

For an inexpensive megaohm tester this did what I was looking for. Our AC quit working and I wanted to check out the compressor to see if it was the problem ( I didn't want an AC repair guy to possibly tell me the compressor was bad when it wasn't and have it cost me thousands). You also need a multi-meter, but between the two I was able to verify the compressor was in great shape. I later tracked the issue to a loose connection in the fuse box and fixed it for free. I would have given it another star for better instructions, but these work just like any other and I figured it out pretty quickly. Is this a professional grade tester? No, but for occasionally testing motors and such, does the job for not a lot of money.

This is an effective entry level insulation resistance tester. It comes with a pair of leads, insulated alligator clips, and enough batteries to get started.The included leads are very flexible and about 3 feet long. The probes are very sharp and include caps to keep them sharp. The banana plus are better quality than I expected, they have four leaves and they fit firmly into the jacks. The included alligator clips just clip on the tip of the probes with a friction fit that is tight and it seems to maintain a good connection.I tested the device on a couple of high resistance resistors that I had lying around and everything seemed to be in range of the devices stated tolerance. I also tested a couple of known good electric motors that I had on hand and everything read exactly as it should.I was also impressed with the instructions included with this tester. This was my first time using an insulation tester and the instructions were translated well enough for me to figure out the basics and start using it.Overall, this insulation tester is perfect if you just need something for a few tests. The price is a great value for what you receive.

After trying to diagnose an instrument that would fail indicating a leakage across the poles, I finally opted to get this little machine in lieu of my generic Fluke multimeter that maxes out at 50 megohm.Had it figured out in no time! Showed 140 megohm between two of the poles, eureka! Was able to clean and replace insulators until it maxed this meter out at 2 G ohms. Instrument works like a champ now!Box is in Chinese, but if you're buying a device like this, you won't need instructions. Display even shows you which sockets to plug leads into for each setting if you're confused.I'm using this device in a professional setting and it's been fantastic. I could not justify spending hundreds or thousands on a Fluke for a device I won't need often.Oh, and do yourself a favor and dispose of the 6 heavy duty AA batteries that come included in the package. All heavy-duty batteries leak eventually, and when they leak, they leak acid. In a device like this that may sit unused on a shelf for many months, you don't want heavy duty batteries in there.

I compared this tester to a older megger I had and they agreed so I believe it is reasonable accurate. I like to test old motors and such before putting into service and it works well for that. Very happy with the product and price.
