You get what you pay for
I bought their 120 hour course because it was one of the more affordable options out there at $25 USD (the other options being in the low hundreds to some even charging almost $2000). I don't have any complaints about the course material itself. The course navigation was confusing at one point, but was mostly intuitive. The disclaimer that needs to be made more clear to customers who are outside of the UK is that depending on the country you choose to teach in, you will need to get your fullcircle TEFL cert notarized by a UK notary and authenticated by the UK government, which can cost 200 GBP+, and can take weeks. I spent 10 GBP to get a hard copy of the certificate, and their customer service people said they would ship it out, but have yet to provide any additional information like a tracking number. They also won't respond to any follow up emails requesting more information. I can't recommend any specific TEFL companies, but I can certainly recommend avoiding this one.
