I was happy with my Alteon B717 endorsement. It wasn't the best endorsement process I've been through but it was much better than the worst.
The CBT was full of good info, it was sad that the monotone delivery was so soporific that I don't know of anyone who didn't fall asleep and have to use the rewind function, several times.
A good chalk-and-talker is better but there aren't so many of them around. The CBT covered all the things a pilot needs to know but missed the nice to know bits.
The Sim time was generic SOP, so one had to forget company SOPs, come to terms with different SOPs for the endorsement process, then revert. In the case of the 717, there was no effective FMS trainer, which was one of the negative issues.
