I think UserZoom is great because it's a good platform coupled with a panel. This is what makes solutions like this shine because building a test is only half the battle, you do have to field the test with some people. Compared with its competitor
UserTesting, it's debatable which one fills faster. We have the ability to launch higher sample tests with UserZoom, which may explain why it's taken longer to fill studies. We also have quant tools, like click tests, tree tests, card sorts, and surveys that we really didn't have on
UserTesting.
I love UserZoom's virtual observation room, where stakeholders can see sessions themselves in real time without having to make themselves visible to participants. This is a big reason why we switched from
UserTesting, which uses Zoom, so all meeting participants are visible to the research participant. The downside of UserZoom is that their video platform is web-based, so it often buffers or lags when people don't have the strongest connection. With big prototypes, like Figma prototypes, it takes a looong time to load.
I also love their method of sending users to prototypes. It makes a huge difference when doing cognitive walkthroughs, where I can reset the prototype myself or bring them to a particular screen on my own, without having to walk them through the path to get there.
Lastly, just have to mention that their screening tool on UserZoom, not GO, is clunky. It's not as easy to screen participants as other solutions.
