im not suggesting any signing devices anymore.
using a hot wallet on your phone is probably safer than using an air gapped, pro, cool signing device that is being advertised as a bitcoin signing device and susceptible to all kinds of supply chain attacks.
if you are gonna use one anyway, build it yourself (seedsigner). or there are apps turning your old phone into one. just open airplane mode and chill.
