A rating looks like proof. It is better treated as a clue.
The 4.9 rating is brand-displayed and no independent platform is identified. The page lists this among its own real gaps. Three testimonials are labelled Verified Customer, Order confirmed.
Without a named source, review count or period, the number is directional only. Look for independent opinions, read recent ones and pay attention to what people say about the refund process. Your own log will tell you more than any average.
