The app posted ads all over the website without notifying! When I wanted to turn these off, the app said that I need to switch to paid plan to turn these ads off.. Hurted my conversion and reputation, be careful with this app!

Saw my own ad today on a webpage after using this for more than a year. My ad had a broken header so it wasn't showing my logo, it was showing old product images from longer than 8 months ago which were removed from the shop way back then when the new ones were put in. They had no idea something was wrong. I'm guessing all their customers are probably affected. I've spent around $1,966 on advertising through them which I reckon I just wasted. They offered me a $25 credit as the remedy for 8 months of showing old product images that weren't converting instead of the new ones I'd evolved massively. Are you joking? Shopify what the hell I expect a certain standard in here.

UPDATE: I see the app has changed its business model and is no longer doing retargeting. It's now an ad exchange, with an option to pay to show ads instead of installing ads on your own site. So I uploaded an an and set a budget of $5/day, but the ad has not spent anything. No idea what's happening or if this app is functional. ---- It works. Assuming your store actually has visitors to retarget, this works and is simple to use. However, I have not gotten a response to any of my messages to Rontar at all -- not emails, not message sent through the app itself. Zero support. Hence the 4 stars.

2024 Edit : I would not recommend this app to anyone. Rontar used to be really good with their google retargeting, it looks like now they have removed that option. Good app for google retargeting, Ive been using this for 2 years with no issue, recently Rontar has double and tripled charge me.... twice.... My limit is $70 recharge when im low, the first time they charged me double $140, I contacted them and they said it was an error and issued a refund. This time I was triple charge $210. This point I may completely stop using rontar and since they always overcharge my account for no reason, the only explanation i got they said it was an error..... I have overall spent $3000 on their service and this is unacceptable.

I just installed this app, so I can't comment on the results, but it literally could not have been easier to set up. I simply clicked 'install', was taken to their dashboard, uploaded my logo, and now I'm all set. Can't wait to see the results!

So far, so good. SO easy to set up. Literally a million times easier to set up than through the Google retargeting platform. It's only been 2 days and impressions are just being served, so we'll see how good the placement/click-throughs are. But you can't beat a free 3000 impressions. Thanks for making such an easy app!

Application is nice but not much visitors yet, probably Coronavirus crisis, people avoiding visit sites who they sell gift items like me or toys, figures, we will wait until this pandemic over but very nice application and I will keep and upgrade after things comes normal or near to normal. strongly suggesting.

This app was incredibly easy to installed and within a couple of days I was getting impressions. That said, my industry is super specialized and it hasn't resulted in clicks, but I think that says more about my industry than the app. I think for a more mainstream product line this would be a sure fire winner!
