This is a most excellent place for technology news and articles.
Have they not heard of the TS100 or the Pinecil?
Both run an open-source firmware and work with any USB-C PD battery pack and still allow you to configure the temperature.
That Pinecil has a 30 day warranty? Not a lot if confidence in the longevity of their product.
My pinecil has lasted for years.
