I prefer these radioddity FS-T1. They actually have an FCC certification. Maybe the extra $10 is too much, but I don't think so.

I love having radios that charge via micro usb!
As for safety, they're probably fine. I mean, they might violate FCC specifications at many baofeng radios do (transmitting out of their licensed bands or emitting interference), and batteries can always overheat, but they're no less safe than any other baofeng radios.
Honestly, they've been selling these radios for years and the sky hasn't been falling. It might be time to allow detachable antennas for FRS radios and focus on cracking down on the interference being emitted rather than on pretending it's important to keep people playing airsoft from transmitting on GMRS bands with UV-5Rs (assuming they can get a handle on their harmonic emissions).
But until the FCC changes the rules, these radios are only licensed for business use by a business that has licensed frequencies that they program into these radios on receipt.
So it's not a safety issue, it's just risking that someone files an FCC complaint against you.
That would be petty and obnoxious, but they'd also have a point that you're breaking the law unless you're using these for business purposes on a licensed business frequency.
Ironically, most of the radios that show up there have a GMRS FCC ID, but are marketed as FRS because they're technically running on some of the same frequencies, and people don't understand or care that you need a GMRS license to use any radios that support GMRS features like higher power, removable antennas, or repeater frequencies.
I suggest these cheap FRS radios if you're going cheap.
It's honestly a pain in the butt to try to figure out which Midland radios are actually type certified for FRS because apparently they want consumers to be confused and use their GMRS radios illegally.
