There are other models and other manufacturers...
None of such stand-alone devices "does not burst from strength". There are two reasons for this:
- they don't really need it and a price.

The real advantage of these devices is that they are intended for this purpose, and thus have adequate holders, are easy to use and quite resistant to weather conditions (heat - sun).
Otherwise, it is always a better choice of a (second hand) mobile phone or tablet.
