High input SWR! Time Owned: 3 to 6 months.
Mine has had a 2 to 1 input swr on two meters since it was new. I thought it was my quite old jumper cables.
After making new ones and testing with a different meter, a different radio new cables and a dummy load. And my antenna I have determined the meter is at fault. So I had to pay $18.The cheapest shipping wet method from Massachusetts to California.The send it back to dywa before the warranty is up.
They said they would either fix it or replace it free a charge. I just hope when it comes back it works as it should.
The company is in a transition. They go under the name of 12voltpower.com. Communications is slow. They told me they don't have time to even open the box of my unit I paid $18 to send back. Sent me a new unit. Apparently it is untested because it has the same issues!
I am done with them.

Good SWR meter Time Owned: 3 to 6 months.
I had enough about scrappy SWR meters and a friend of my advised this meter. And it was a good purchase.
The swr and power are spot on, compared with a Bird meter.
For the money (€125) it is a good meter. I wished I bought it at first.

SO-239 Sockets too big Time Owned: 0 to 3 months.
I bought this meter and a new antenna at around the same time. Had all kinds of random VSWR issues that made no sense. As in 5:1 to 3:1 depending on an antenna tuned and verified to be well under 2.0:1 and that includes from the end of the feedline. It wasn't until I acquired a good Antenna Analyzer and dummy load that I figured out the issue that was wreaking havoc and making an otherwise good meter a piece of junk.

The SO-239 Receptacle for the PL-259 Center Pin are Over sized for the Antenna Connection.

Sloppy fit with every PL-259 I had on hand. Zero Resistance as the connector went in. BUT If I positioned the jumper just right or tweaked the cable, when connected, just right, my VSWR indication would make sense.

I plan to overcome the issue by Tinning the center conductors of the jumpers I use.

The other Receptacle for the XCVR side is slightly smaller and makes a decent connection.

You can actually look at the two of them and detect a difference with the naked eye. Maybe something happened in the Testing phase of the manufacturing process. Who knows.

Good meter otherwise, but if you get a unit with Cheap Sloppy SO-239's receptacles, hopefully you don't pull your hair out for too long before reading this review.

UPDATE 10/31/2021. I Tinned and groomed the PL-259 center conductor of my feed line to a perfect fit with the meters SO-239 receptacle. This meter has turned out to be very accurate on 2M thru 70cm in both High and low power modes. SWR reading are very consistent with my RigExpert AA1000. If you are having some flukey readings, I strongly recommend taking a look at those SO-239 receptacle sockets. 73/Mike KC7MAW

very nice Time Owned: 6 to 12 months.
have had mine about a year now, and must say it is a nice compliment to the shack. good looking,accurate,and seems to be very well built.cant be beat for the price!! wouldnt hesitate to buy any daiwa products at all. i use this meter on a ts2000 and a icom 9100 both for vhf/uhf applications . nice to see my antenna swr and power output at all times. the lighting is bright and from the bottom of the meter...excellent. ide buy again.
