Great app and good service if you need help!

— Sound by Sweden

Good app that does what it promises. The functionality works well and is easy to use. The support team was particularly helpful whenever we had questions and responded quickly with useful solutions. Overall, a positive experience.

— vannbells

Excited about this app. Seamlessly integrates into our pages and follows our design formatting. The team was very responsive in helping me get it set up properly.

— Cast Jewelry

Great app. I had a bunch of products out of stock and this app paid for itself as soon as they were back in stock. The customer service is also superb. I tried their pre-order option that they introduced recently. It had several serious bugs but after I reported these they went to work and solved them very quickly. I'm a happy camper.

— Rolling Mavericks

Since enabling Pre-Order and Back-in-Stock alerts, we stopped losing sales when items sold out. Customers now reserve products or get notified immediately when they're available!

Very quick and prompt support from Vishal

— Abstract Aromas

By far the worst/most broken and poorly functioning/glitchy Shopify app we have ever downloaded.

— Saint Oral Health

3rd class app do not use this app useless app

App is offline and we lost all our subscribers

— Vintage Suppliers 1989

Your company's advertisement in my website footer, without my approval, is a serious issue. I will be uninstalling your service due to this disrespectful practice.

— Bruno Cycling

The app isn't free. Beware. The starting rate is $20 a month and they charged us even though we never used the app and only had it installed for less than 15 minutes. Update: The app developer refused to refund us unless we deleted our truthful review. I have now reached out to Shopify support in order to try to obtain a refund. Update: I am still working with Shopify to get the charge removed....
