Celestron CrossAim Reticle Eyepiece

Product is okay and does the job well however a little poorly made.
When I first used the eyepiece, turning on the light for the crossaim it seemed to turn the compartment where the bulb is stored which then made it difficult to turn the light on and off.
The second time I come to use the eyepiece the light would not work. I assumed I left the light on after its first use and had not switched it off properly. I bought new batteries but it still wouldn't work so there was an issue with the connection of the bulb compartment to the battery compartment. I opened the compartments up and stripped back the plastic coating off a wire to give a better connection.
It now works fine.

Neat product: does the job.
