User Reviews

User reviews are mixed. The add-on helps users find coupons and save money, and several accounts report earning cashback and discovering better deals. However, it often drags down browser performance, with slow loading and frequent unavailability of coupons. Many reviewers worry about privacy, citing data collection and tracking. There are also reports of cashback suspensions and perceived scams, plus intrusive, hard-to-disable notifications. Some users still have positive experiences and find it useful, but reliability and privacy remain major concerns.

Pros

Finds good coupons and discount deals, helping users save money.
Cashback feature yields payouts and visible savings for many users.
Offers deal search and price/offer comparisons to help choose better offers.
Some users report it being helpful overall and saving money on purchases.

Cons

Major impact on browser performance: resource intensive, slows or freezes pages.
Coupons are frequently invalid or not working; many links are broken.
Privacy concerns about data collection and possible data sale.
Risk of cashback suspension or account issues with support being unhelpful.
Intrusive notifications that cannot be fully disabled or managed.

Recent reviews

Okay, so normally I don't care about giving reviews, but my latest purchase just blew my mind. So far every now and then I've saved 5-20% off my goods, which is already quite convenient. Just a few days ago however, I saved a whopping 60% on a big purchase! What would have cost me 237,26 € went down to 94,90 € through this app. I saved 142,36 €!! I started to feel guilty, because I'd just save so much money... That felt like a steal. I actually had to look up the ethics on this via the internet, but apparently companys have those coupons all planned out and I'm very much welcome to use them... Anyway. So I am getting my package in a few days and I'll gladly keep on using this app, which is really easy to use btw - most of it is working automatically. Kudos to the developers for helping so many people save so much money!

Pues parecía en un principio una mala app, y resulta que no, me acabo de ahorrar en un pedido de 75€ unos 26€ ! Lmao con que me ahorre algo de vez en cuando me da igual que me roben la privacidad de mis datos, si necesito entrar en alguna página importante lo hago en modo privado o desactivo la extensión hasta que me haga falta, me parece todo un acierto la verdad
