Bests & Worsts Reviews from Amazon

Arrived with no apparent damage; assembled per instructions, along with the AC adapter as noted in other comments. After on-to-two minutes the up/down buttons on the controller did nothing, making the alignment process impossible. Even just turning it on and skewing to a visible object, same thing. I sent off a detailed support ticket to Celestron (thorugh what looked like a third-p;arty service), and have received nothing -- not even an acknowledgment. Two days later the support ticket web site returns "page not found." I've had a number of telescopes over the years, and long yearned for a Celestron SCT. Now living in the southern California desert, it seemed like finally the right time. Given the apparent lack of support by Celestron (as well as some comments here), I'm sending it back for a refund and will probably try a Mead instead.
