Claims to give cash back on online shopping, I've tried it multiple times and it has never worked. Contacted customer support, they were extremely uncooperative, kept making excuses, deflected, and strung me along for more than a week worth of customer support messages. I've also seen real reviews that say their donation system to charities is highly suspect and most likely a fraud. Please avoid this fraudulent extension at all costs. I've used many other extensions that have worked perfectly as advertised. Attaching the email chain their CS strung me along on, for what would've amounted to maybe $5 worth of cash back. Absolutely $#*!ing ridiculous.
