Didn't work
This product would be very good if it was reliable. It took a lot of attempts to connect it to either my iPhone or my Android. Then it could not hold the connection. It would appear that Celestron were having problems with this model but have now upgraded it. Selling on line at around £150.00 it would appear to be expensive for what it is, - although I think it would make controlling Celestron telescopes a lot easier than the handset supplied.
The seller was excellent and responded promptly with suggestions as how to solve the problem. I had no problems with returning it.
