I will change my review only because on a 1998 Audi A3, due to a curvature at the antenna spot, I was not able to stick it so that there are no gaps on the side. I tried very good double-sided tapes and other methods, but unfortunately it does not sit properly. On the other hand, I noticed that especially during trips between mountains, it has no signal at all compared to the factory one, that's why 2 stars

Installed on a Toyota Yaris.
Very easy installation.
The antenna works great.
The double-sided tape that comes in the package needs some attention, it is not of good quality and it comes off. It came off on the second day. I replaced the tape with a good quality one and it works fine.

Very good choice but its glue is not that good, we got another one from a local store!

In Yaris, the product is excellent. It captures all the stations inside/outside. I had already read before and bought a strong double-sided one since the one included in the package is not good.

Really a cheap and good antenna for the car. Those who complain about the application in the front, I did some actions empirically (with a heat gun) and managed to stick it on a Ford Fiesta 2006-2008. If you have a heat gun, you will be 100% satisfied with the adhesive tape, which at first glance does not convince.

In two cars that were tested, it did not perform well and a very short 3cm antenna was used with a shark fin as a cover to protect the base of the antenna.

I painted it in the color of the car and installed it easily, and the stations come in well. The only negative thing is these double-sided pieces it has, they don't stick at all, you need to buy a good double-sided tape.

Very good. It helped a lot and the photo that someone put in the comments is not like the photo above, but better. It has a rubber base and makes a slight curve. I reinforced it with a little more double-sided tape and it applied perfectly and with the rubber, nothing is visible. As for the radio, at least in the city, I didn't notice any difference compared to the factory antenna.

It has a slight curve to fit the majority of ceilings, however, the tape that comes with it is not reliable. It is good in terms of being an antenna because it has an extra IC Chip inside.

EDIT: After 1 month, I stuck it with my own double-sided tape. The adhesive is a joke. It is worth the money, but also get some glue

If someone has a flat roof, the plastic ones won't fit because they are inflexible. Therefore, if your roof doesn't have the same curvature as the product, it won't fit

I definitely recommend it without hesitation, it is very good and the adhesive is very strong. I bought it 3 months ago and it lasted the entire summer without fading or anything. As for the signal, it captures better with this than with the regular antenna. It is easy to install without any problems, and if you remove it, the adhesive comes off easily. It can withstand water, washing, and sunlight, and it is very good

The signal on the radio is fine, it didn't get worse as I feared and it stuck perfectly. Time will tell how long it will hold.

Edit after about a year. The adhesive is still strong and stable. However, the signal it captures becomes slightly worse. If you live in a rural area, you may experience some interference in certain spots, whereas with the old antenna, it didn't happen. Nevertheless, if you decide to remove it, it doesn't leave any residue and comes off easily.
