An honest description makes room for the reason someone might choose something else.

A description that admits nothing against itself cannot be trusted. Saying what a thing is poor at, and naming the person for whom the other option would be better, tends to increase belief rather than reduce it, because you have shown you are describing instead of selling. It also spares you the customer or friend who takes your word and then finds the gap. Honesty of that kind is expensive once and cheap thereafter.

Next time you recommend something, name one situation where you would recommend the alternative. Watch how differently the recommendation lands.
