I've had one of these for a few months now and I liked it so well I got a second one for one of my other radios. I particularly like being able to calibrate it on screen with my bird meter and then bob's your uncle. I also like the user configurable swr warning. Very nice. Over all my one suggestion is make one for vhf and then I'll buy a couple of those.

I have had this wattmeter for a couple of weeks now and really like it. Easy to use, accurate, and does exactly what I needed.

The product description makes no mention of product instruction sheet or required charger. User must purchase charger separately and read product instructions from AMAZON webpage. Not acceptable.

Found that unit would suddenly shut off and reset while transmitting on 50 watts of use. Battery fully charged and not any connection issue. Would work for 2 to 5 minutes and then reset, without warning, and then may go 1 or 5 minutes until it would happen again. Usually during TX mode, others while in receive mode. Could not investigate anything internal (poor connection?) as seal cannot be broken for examination or no warranty. Returned for refund. Heard other operators with same on/off reset issue on other forums. Cause??

This SWR/Power meter, makes a bad hash which shows up on your receiver. It also has a tendency to shut down while in use. There is no peak reading available, just rms. The lettering on the front is crooked. I only asked the manufacturer to give me updates on remedying the hash problem, as I would try to fix the problem myself. I got a string of Chinese caricatures for a reply.
