Here's our story. We run a podcast and people have begging us to do a course. So, we started looking into putting one together. We researched all the available platforms and decided on the best one we could use with "most" of the features we wanted. Not happy with the sacrifices we had to make, and not happy with the limits. What we really didn't want to do was have to switch later and learn yet another platform.
Setting up the course in the other platform was a nightmare. We couldn't see how it looked, the builder was not intuitive, we couldn't combine things, it was awful. Luckily we were only in a trial.

Then we heard about Heights.
Okay, no kidding we did our homework before getting this. As I said, we don't have to switch later on to learn a new platform. We spent 4 hours researching everything to get all the pros and cons. There's a couple of cons we can live with. Eh, the landing page could use some work. We would like to see an upgrade option to a higher course option and not just a digital product. Can't wait for the module section to roll out so we can break the courses down into smaller chunks. The course duplication will be a godsend when it comes out since we want to just add to the courses we are already building.

Anyway.

What took us over a month to do in the other "more popular" platform, took us mere minutes to do on Heights. And that month of work on that other "thing" called an LMS, we didn't even finish because of the limitations and complexities. From scratch and no copy and pasting, we got our entire course laid out. I was taken aback by how simple it was. Being able to see how the course looks to the client without completely exiting is awsome. Being able to mix things up adds so much value to the course for the person laying out their hard-earned cash. We wanted to build honest value and the other platform simply limited us to some cookie-cutter looking thing that made it feel cheap. Not here, not Heights. Other LMS's are going to be trying to copy what the Sumo team has built here.

This has nearly everything we were looking for in a course creator and more, even with the cons I mentioned. We could not be more pleased to grow with Heights and the Sumo team on this.
If you are looking anywhere else, trust me, you are wasting your time and possibly lots of money.
I believe we have found a course home. No need to go anywhere else for a very long time.
