I am looking at purchasing a heat/gun blower to replace my Surface pro 5 screen (warm the adhesive to weaken it)….as well as for other electronics. I have come across 3-in-1 Function Heat Blower and Soldering Iron (see link below), which I thought could be helpful with other projects also. https://www.jaycar.co.nz/3-in-1-function… Has anyone had any experience using this type of “heat blower”? First thought is it may be difficult to control the temperature…although it does have a flame adjustment setting. Thanks in advance for your help.

I think the soldering gun you picked will be to narrow an area and far to hot to do the job well. I believe you chances or success on this repair would be much greater with a standard heat gun: Heat Gun

I would use the iOpener or a heatmat.
