TXQ (MyDel G63) UHF Mini Walkie Talkie. 400Mhz-480Mhz: Is it any good and who is it for?

I was asked about a simple 2 way radio recently that could be used in a basic home prepper kit. I found this, a realy tiny radio from TXQ (branded MyDel) https://www.hamradio.co.uk/g63

its a great little radio, really simple and very easy to program. I would program it for UK PMR (not strictly compliant) but for an emergency radio could be very useful to keep in contact with a family member should the lights go out with no phone signal. Its cheap! at £49.99 it offers really good value with a touch of quality, it will also charge from a USB power bank..
