Class II — the FDA judged the product may cause temporary or medically reversible harm, with a remote chance of serious harm.
This is the FDA's risk judgment for this recall. It describes the potential of the product as a category — it does not establish that any specific unit harmed anyone. Most recalls are Class II or III.
PiezoWave 2 Control Unit, Product Number 100506US, compact myofascial acoustic compression therapy device that enables treatment with piezoelectric shockwaves (Therapeutic massager).
Why it was recalled
The high voltage capacitor may fail early in the product life cycle after delivery of surge voltages. When this failure occurs, the capacitor may produce smoke and a burning smell. In extremely rare instances a capacitor may cause a spark or excessive heat when an internal capacitor failure occurs.
Is your unit affected?
The recall covers only the specific lots or serial numbers the FDA listed. Enter the lot or serial number from your product's label and we'll check it against that list.
A match means your unit may be covered — stop and call your pharmacist before doing anything. No match suggests it isn't covered, but confirm anyway: code formats vary and lists can be incomplete. Your unit not being listed does not guarantee it is safe, and being listed does not mean you have been harmed.

What this is — and is not
A recall is a recorded FDA enforcement action — the FDA logged that a firm is removing or correcting a product. It does not establish that any specific unit harmed anyone, and causation is not established by a recall. The class above is the FDA's risk judgment for the product category, not a finding about your unit. This page informs and compares; it is not medical advice and never tells you to start or stop a drug or device.
