For me it became essential after a similar experience. I once bought a door that looked solid in photos but felt hollow when installed. Ever since then, I always visit a showroom to check things like hinge strength, insulation thickness and how the door closes. It also helps to compare finishes side by side instead of guessing based on images. You should
check this door collection to see modern designs. Being able to physically test the movement tells you immediately whether the construction quality matches the marketing.
