These were tiny dual-band FM handhelds produced by Yaesu.
In the past I have used these (I have a VX1 and VX2) on both 2m and 70cm simplex and repeaters. Many found the supplied antenna not as good as they could be and they replaced these with better ones.
These days, many have bought much less expensive Beofeng units, although the quality control on these seems a bit hit and miss.
At the moment the Chinese manufacturers seem to have work to do to get amateur radio products to the same consistent quality we are used to from Japan. They will get there, but it may take a few years. When Chinese products get to the same quality and consistency we are used to from Japan the Japanese will face serious competition.
