Just took delivery of my Telrad this week.... first light last night. Great piece of kit, especially for a dob with a right angled finder - saves a lot of ginning around. Between the moon light and wind last night, I really just sighted it in and played around, but was very impressed! Don't know why it took so long to get one....
They are a lot bigger in "person" too.
A hint: don't forget to turn it off - just turned mine off then!
There's 14hr of battery life gone!
