This is actually quite a common civilian or secondary allocation range in many places. Search "430-" here life.itu.int/radioclub/rr/arsfoot.htm

The people that work at Xiaome know their markets.

I wish someone else aside from snooping Chinese company would release something like this and for a good price and with EU legal frequencies.

430-440MHz is a weird allocation. In the UK (ITU region 2) it's users are military (primary user) and radio amateurs (secondary users).

In other ITU-2 countries it is likely to be similar, but not guaranteed. Usually UHF radios are designed around 450-470MHz or 430-450MHz to capture the maximum number of commercial users in as many countries as possible while ensuring they are filtered adaquately to prevent unwanted RF entering or leaving the radio.

For the UK market these are only useful to radio hams, the military use just isn't there. This is probably a product to test the market or something they will release in country/region specific versions.

I don't see many people buying these in any capacity.

It is worth mentioning that the frequencies this covers are not licence free and you must have an appropriate licence in order to transmit. You could get yourself into a lot of trouble if you were to randomly choose a frequency and start transmitting. In the UK, have a look at the Ofcom frequency allocation table

and, for details on the only ways you are allowed to transmit here with this radio as a civilian, the RSGB bandplan for 432MHz

For other countries, contact your national amateur radio representative body and/or the Government body that administers radio licencing for details.
Sorry I'm a new poster so no links for you.

Doesn't work in the Commercial Band of 450MHz - 470MHz. Commercial Band is utilized by the major communications manufacturers for professional grade radios. Construction, manufacturing, high end hotels, cruise ships, schools, to Public Work Departments and even some Public Safety workers utilize this band. The radios are usually manufactured to stand up to the wear and tear that customers deal out. These radios are nothing more than cheap plastic made to look like a million dollars but don't offer the features found in Motorola or even Hytera radios. Also only programmable to a small range of Ham Band freqs (Amateur radio operators). Best uses are probably four a family on vacation or on a cruise together to where they could separate and still communicate to keep in touch. Even use on a cruise ship will be tough with only four watts transmit power You might not get the range you expect.

I thought it at least would be some kind of cyberpunk for a walkie talkie in the year of 2023. Who would buy a mundane walkie talkie at $44? Definitely not companies that do on-site jobs. Will hikers like such a thing?
