I am giving a second star because it's a free app. I was glad to find something with so many good reviews, but let's be honest, none of the reviewer has really use that application... its not possible.So i will try to write something accurate.
After 2 weeks using it, I have asked few things to the support, and still waiting for good and helpful answers.
Regarding the application, its not very user friendly. After importing a product, you can't:
- select image you want to delete/add
- split product
you have to do that from your Shopify store.

Then when you want to modify a product, it's the same problem, you don't have many possibilities from Dsers APP.
If you want to delete a product from Dsers, it doesn't give you the possibility to delete it from Dsers AND Shopify or just to delete from Dsers. (option available from all other app)
So when you want to use another app, and when you delete your product from Dsers, all products are removed from Shopify....
To linked a product from Dsers app, its a big mess... You have first to push it in you store, and you must activate your product in you store. You can't modify a product which is not yet shown in your store.
To link a product from you store to Aliexpress, here comes the funniest part. Its just amaizingly complicated. Specially when you have product with multiple variants.
you have to press many butons until you finally manage to do what you want. And even when it's done, you are not sure that its correctly done, because the design is not easily made.
After the variants are linked, you have option to choose what will be the shipping method for each variant, which again.. leads you somewhere you don't know exactly where to press, and if you have to do it... its very confusing. because you can also create a shipping method in your Shopify page.
I forgot to speak about the pruducts prices which leads me to remove this application.
There is no update of the price. When Aliepress changes the price, your product cost in Dsers doesn't update.. even after re-linking your product.
And the price and cost shown in Dsers app ended to be completely different when you have multiple variants.
Dsers is doing a lot of advertisement about the bulk order.
They are explaining that you can pay 100 products in less than one minute. I must admit i didn't go till this process, so i didn't have possibility to try the bulk order. i will not comment this part.
Hope my comment will help some, and hope that the dev will design and improve that app.

DSers is the best alternative to Oberlo. With DSers you can bulk order and fulfill, and you can also bulk pay for up to 90 orders in one payment! So far everything with DSers App has been easy to use, and if you get stuck they have a real person on chat messenger to help you. One more thing to mention is that DSers is THE OFFICIAL dropshipping App from AliExpress, this is no third party App, it's OFFICIAL!! AND IT'S 100% FREE!!! Enjoy :-)

This app is incredible! It helps a lot to simplify the creation of orders.

Nevertheless, It would be amazing if the app could sync the inventory stock from the suppliers instead of notifications.
