A noticeable improvement over a Nagoya Time Owned: 0 to 3 months.
Having switched from what I believe to be a genuine Nagoya 771, this antenna is a noticeable improvement.

I'm able to pick up signals on the 2m and 70cm bands stronger and clearer using my Yaesu FT-65.

I've been able to hit nearby repeaters better than before and feel for the money I paid for the antenna (£22 over the £8 I paid for the Nagoya) it was worth upgrading.

Meant to be a wide band scanner antenna Time Owned: more than 12 months.
So-so as a ham HT antenna which it was not designed for. It works well covering 50-800 Mhz as designed for. It has a center of about 108-250. It claims to be usable to transmit on 2,220, 440 etc. but was never designed for this although you can use it somewhat in those bands. Its a scanner antenna meant for receive only.

Better gain than the Alinco OEM antenna Time Owned: 0 to 3 months.
I've mounted the Diamond SRJ77CA on my Alinco DJ-VX50 HT. It receives noticeably better than the Alinco factory antenna on Commercial Broadcast FM, 2-meter, 70cm, and the GMRS bands. I have not yet experimented with the AM air-band reception. I haven't been able to receive any of the Weather-band channels at my remote mountain/valley location. My only physical concern for this antenna is that the rubber base skirt leaves a 1mm gap of SMAJ antenna connector brass showing when screwed into the Alinco HT, so that defeats the HT's IPX67 rating. Perhaps Diamond antenna will lengthen this rubber spacer-skirt someday for a better fit. Meanwhile, I haven't found a thin-enough water facet o-ring or a rubber flat-washer of the correct diameter & thinness to fill the gap. Regardless, this antenna is a keeper for me. The Alinco DJ-VX50 is definitely a keeper too.

Poor performer Time Owned: 0 to 3 months.
I bought one of these from a reputable supplier in the UK in the hope of improving the signal from my FT-65E. No dice. So I measured it compared to the stock 6.5 inch Yaesu rubber duck.

VSWR on 2m is no better than 3:1 (Yaesu 1.4:1)
Transmit performance is 2dB DOWN on the Yaesu

Either these antennas vary a lot between samples, or I have a fake from a reputable supplier, or a lot of folks are deluding themselves.

It may be a tad better than a Baofeng standard antenna but it is significantly worse than the Yaesu.

I have requested a return

Poor on 2 meters, Average on 70cm Time Owned: 0 to 3 months.
I tested the antenna on my AnyTone D878a and it performed poorly on 2 meters and average on 70cm. The antenna that came with the AnyTone performed much better.

Excellent Hi Gain Antenna Time Owned: 3 to 6 months.
Makes my Yaesu FT 4XR Rubber Ducky seem just that ie a Rubber Ducky :)
Can hit some local Repeaters with 500 mw.
Solid and durable.

Not a bombshell, but solid Time Owned: 3 to 6 months.
I was psyched when I saw Diamond's claims of 6db gain "Rated against typical stock HT antennas." But that sort of gain would be equivalent to turning my 5w HT into a powerhorse. And that didn't happen. But it's a nice , flexible antenna with a (so far) strong SMA connector. And it was only a $20 investment or so, so trying out another is not going to blow the bank, either.
