A 4.7 average across 2,847+ reviews is a strong-looking number, and it is shown without a source.
No link to a review platform, no breakdown of one-to-five-star counts, no dates and no explanation of how reviews are collected or checked. We cannot say whether 2,847 is every review or a selection, or whether it spans one product or several.
A rating the brand displays about itself is a claim, however sincere.
Give it little weight alone. Look for reviews somewhere you can read the full range of scores and the text behind them, and prefer ones that give timelines and mention downsides. Then rely on your own log, since your own result is the only one that applies to you.
