I got these to pair with the iFlight Crystal patches on my goggles. My main reason for these and the patches was the low profile so I could easily store them in my bag without removing the antennas. These little omni's work well and keep things nice and tight for easy storage.

They do seem a little fragile although I have yet to break mine. The casing is very thin and do not seem as durable as other alternatives such as my Foxeer stubbies. I am sure there are better options for reception as well but these combined with the patches still perform better than stock antennas for myself and I am happy with that along with the smaller profile.

I switched back to the stock antennas, I think they give slightly better reception. these antennas look cooler and have a lower profile though if thats something you want

I bought these because they were inexpensive. They work great for builds.
