You pull up outside a nightclub.
You’re driving a brand new, top of the range, Mercedes-Benz, which just so happens to have a headlight out.
When you get out of the car people don’t say “hey nice car”, they’ll tell you you’ve got a broken headlight.
The same applies to your product – If it’s broken, users won’t care how good it looks.
Make sure the basics are working first before you go showing off in front of everyone.
