Sealing A Exterior Door

N.Schiffer

I'm going to weather stripping 4 door in a historic home and we have decided a low visible setup would suit the home the best, to keep the elegance. So My plan is to install a rubber seal in the corner of the jamb and I came across this tool

page 8, it was also featured in FineHomebuilding

along with this drop down threshold seal

Just looking for opinions on it, and if anyone here has used either of these products.
