The Theragun PRO (Gen 5) is a high-end percussion massager used for recovery and pain management, often in high-frequency sessions. The common long-term issues are mechanical and battery-related: battery packs lose capacity, motors can develop bearing noise, and switches/trigger controls can become intermittent.
The attachment mount can also loosen if used aggressively, and charging ports are vulnerable to strain. Repair is usually worthwhile when it's a battery replacement or a known modular part fix that restores smooth operation under the threshold, especially if the device is otherwise in good condition.
Replacement becomes more reasonable if the motor assembly is failing, if there's excessive vibration indicating internal imbalance, or if repeated repairs are needed for different components. Because these devices are used on the body, consistent performance matters; if the unit stalls under load or overheats, prioritize safety and reliability over marginal savings.
