I want to say: This is a failure, you should use a blimp
Which of the following should it be:
- This is a failure, you should use a blimp
- This is a failure. You should use a blimp
- This is a failure. You should use a blimp.
Keep in mind that if we go for the last one, which looks the best, it becomes inconsistent with one sentence error messages, which usually don't end in a dot.
