From reading reviews of the phone mounts that rely on adhesive, e.g., Spigen and Jowua, a lot of the negative reviews indicate the adhesive ultimately failed, particularly in the heat. Wouldn't the Magbak have the same issue?
I've been using a vent mount similar to
this Temai-branded one, which has worked relatively well. However, I have been in search of a magsafe/magnetic solution, and I've ordered both the dashboard and screen mount Spigen Onetap. I like the idea of it being screen-mounted, but I worry the adhesive will fail, particularly during these hot summer months.
