Advanced product ratings plugin

This reviews plugin is extremely robust and allows for a lot of advanced customization that isn’t hidden behind a paywall. You must be technically literate to take full advantage of what it can do, but even the free support offered here is top-tier.

While there’s plenty of documentation, it’s scattered throughout the plugins settings menu. If there’s a standalone and more easily searchable reference, I wasn’t able to find it. This can be a drawback if you intend to implement advanced functionality that can’t be enabled with a setting. Again though, the developers are here and willing to help.

If you’re a novice, I’d recommend purchasing a license. You’ll be in good hands.
