When we encounter a situation or object that is of no use, it can be frustrating and disappointing. Luckily, there are a variety of synonyms that can be used to capture this sentiment. For example, the phrase "worthless" can be used to describe an item that has no value or use. Similarly, "ineffectual" can be used to describe a strategy or approach that does not yield any results. "Futile" and "fruitless" are other options that convey the futility of a situation or action. Ultimately, whether you use "of no use" or one of its many synonyms, the message remains the same: something is not serving its intended purpose and is therefore not worthy of attention.
