Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers like the signal quality, ease of use, magnetic strength, performance, and size of the antenna. For example, they mention it gets decent reception, helps with transmit range, and is easy to mount on a steel rooftop. That said, some say it works great for mobile comms and fits into portable units box perfectly.

This thing is enormous. The 5" magnet really wants to stay in place. I use it with a half-wave VHF radiator that has a thick loading coil at the base, and it works beautifully, The bottom of the magnet has a heavy rubber rig around the lip, and a felt-like pad in the center to protect your car's finish. Honestly, I'd prefer an all-rubber coating, since I leave it on my car in all weather. I'll see how it holds up. I park indoors, so I'm not too worried about the felt. The mount includes a threaded rain cap, but if you're concerned with moisture, why not remove the entire mount and toss it in the car? The attached cable is slightly longer than the UT-72's, but not long enough to be annoyingly lossy. I find the extra couple of feet useful.
The following is in regards to the UT-72 antenna:
I own two of these antennas. The original was intended to live atop my Subaru Crosstrek, but I had such a positive experience initially testing it with my base rig, that I opted to leave it there and order another for the car. My home station is based in a small office, in a rental apartment with no balcony. My antenna options are thus _very_ limited; use a UT-72 and some DIY Yagis for VHF and UHF ops, and a random-wire/balun/choke for HF and shortwave listening. Everything is set up indoors. With some luck, I'll eventually work out a safe and discreet means of getting the random-wire out a window. I digress.
The UT-72 requires a good ground plane, as mag mounts do. The more conductive surface area underneath the base, the lower SWR and better performance you'll get. My indoor unit is stuck to a large window A/C (of course my landlord has the compressors mounted entirely in our apartments, leaving nothing outside to work with), and my mobile unit is centered behind the sunroof. If you just need a temporary hack, sticking the magnet to an overturned cookie sheet is better than nothing. Mounted as intended, the SWR lives up to vendor claims. I'd be happy to take measurements for a particular frequency/frequencies and post photos of my meter. You can reach me at the address in my profile.
In terms of workmanship, this is a rugged antenna. The base is huge—there's no way it's going anywhere at highway speed—and coated with a heavy layer of protective rubber. The thick coil at the base does double-duty, improving broadband coverage and acting as a protective spring. I take every precaution driving places with a low overhead clearance, but I'm confident in the UT-72s ability to flex upon bumping into things, without sustaining damage. The included cable is long enough to run back through my tailgate and up to my mobile rig, and the SO-239 to SMA-F adapter is a nice bonus that facilitates connection to the majority of HTs.
If you're shopping for a magmount, I highly recommend this antenna.

I get it. Having the customer pay for return shipment probably avoids a lot of fraudulent claims, but when I could provide proof in the way of pictures??? OK, then, how about this: Have the customer pay the return shipping, then reimburse them if the product is actually defective. Don;t worry, I won't hold my breath.
I have since repaired the antenna base using E6000, a flexible adhesive of the type Nagoya should have used in the first place. A Comet CA-2x4SRNMO antenna now resides as a semi-permanent fixture atop my truck, so the UV-72 will be relegated to the go-bag or stored in the back of my wife's Jeep for use in emergency scenarios. I'm sure it will hold up fine under those conditions. (Yes, that was sarcasm.) I can tell you, too, that it's likely the last Nagoya product I'll ever buy.
EDIT: I'll add that the magnet on this antenna is suitably strong, and holds very well. In conjunction with the spring, it's able to bend over with only about 4" of clearance, and not be knocked loose.
