Good value meter that gives repeatable results
For the money, this meter seemed like it would do all that I needed: show how much power my radios were putting out and, more importantly, help me decide if various antennas were effective when I used them. To this end, I put a given antenna on the meter, connected it to the radio and keyed the transmitter. (Note that you have to follow the instructions when you do this. You have to be holding the metal case of the meter to insure there's a ground plane--as shown in the pictures and described in the user manual. Failure to do this will result in erroneous data. I took notes of the antennas used and the frequencies tested. I mention this because I have seen reviews of similar models where people complain about inaccuracies without mentioning that they are testing properly.) I can't give positive proof that the meter is accurate because I don't have a meter to compare it to. (That's why I had to buy one--I didn't have one.) But in the setup described above, I was able to obtain repeatable readings even when I would change frequencies. Each time I returned to the same frequency/antenna combination I was able to get a reading very, very close to the previous one at that frequency/antenna. This makes me feel that things are working properly. I was pleased with the assortment of connectors and adapters included with this meter. I did not have to purchase any others to do my testing. I was also pleased that the kit included a dummy load so that I could check the power output of my radios. Again, I can't vouch for the accuracy, not having another meter to compare it to, but I was able to get consistent readings for any given radio at a given frequency and the readings were about what I expected the radio to produce so I'm inclined to believe that the meter is good and probably more than accurate enough for my purposes. Overall a good value. The meter works, is easy to use, gives consistent readings that appear to be correct and includes a good selection of accessories that highly increase its usefulness.

GREAT piece of equipment!!
This is a great piece of equipment. I was shocked at how many of my HTs had horrible antennas that came stock. I mean an SWR of 2.0 is something still usable but 6.3 or 11 is unacceptable. Needless to say, I corrected the problem antennas and the involved HTs are transmitting and receiving so much better. I'm just glad I hadn't burned one of them out yet.

Great affordable meter especially for handhelds
I wanted to upgrade from an old analog meter I had and get something specific to handheld radios and am very happy with this meter. It’s very easy to use, allows you to quickly test swr as well as power output, and has a variety of adapters, dummy load, etc so you can make any connections work. I also like that it’s rechargeable so no batteries to deal with. Definitely recommend this meter for anyone looking for an affordable but quality meter, especially for use with handheld radios.

Easy to use. No calibrating.
I like this digital meter along. No calibrating needed. Comes with assorted connectors & a dummy load.

Decent way to test your radios.
Assuming this is accurate, it seems to work well. I don’t have anything else to measure it against. You do have to hold the unit while you transmit if you’re checking the antenna vswr. This is a weird variable, and seems to have some room for error. I try to do EXACTLY what is pictured in the manual. Seems to hold a charge for quite some time, and is very compact. So much so that the box it comes in is over the top big.

Works well and seems accurate.
This SWR meter worked perfectly. I was concerned that this meter and my other larger SWR meter would generate very different readings because I have a friend who has 3 different meters that read far enough apart that we can't rely on their readings. One would say the SWR was near perfect while another would say the antenna was barely useable. I tested my radio with the dummy load provided and got an SWR of 1.01, a near perfect score, and a power reading of 6.86 watts. I took an antenna that I had tuned with my other SWR meter and got an SWR reading of 1.01 and a power reading of 6.9 watts. Checking my notes from tests with my other meter they are identical or nearly so. I'm ecstatic.

Can ya HEAR me now??
Very handy for PWR and SWR verifications... Checked against another unit and almost identical outputs, but this one is a lot easier to use.

Good quality
Great meter for the price and comes with a few connectors
