What do you like best?
The user interface is by far the most intuitive of any data loading product I have used, which means uploading data with Dataloader.io takes significantly less time than with other products. We have even trained a few non-admin users on how to upload and they were able to pick it up quickly too with minimal training.
What do you dislike?
There are certain times of the year when we quickly hit our monthly limit, as a nonprofit we can't justify paying more to increase the limit when there are other products out there we can use for free.
What business problems are you solving with the product? What benefits have you realized?
Getting better, clean data in the system and easing pain points around data entry in Salesforce by using bulk uploading. Overall, the general feelings around getting data into Salesforce have improved because people have options of how to do so and which option is best suited given the scenario.
