I love that it's very easy, intuitively designed with many useful features like creating polls as well! It has helped me create surveys in less time than other tools we've used before by allowing us more control over our questions/polls without having any coding knowledge or experience required (which can be quite daunting!).
The support team are also great - quick responses whenever you need them which helps keep things running smoothly when working remotely from home during COVID-19 lockdown times too :) We have been using pastels primarily so far but there isn't anything specific i dislike about this tool yet apart maybe being able see how much people take part of each survey? But overall everything works fine atm & no complaints here!! Have created multiple different types / sizes etc within minutes really easily compared w previous solutions requiring lots longer hours spent learning new skillset needed along side code writing expertise if applicable.. Our main use.
