I received the KMS UFO light for my Lee Classic Turret. Followed the preparation instructions to the letter, but still had some difficulty getting the light to stick. I used some edge clamps to hold it on for a while, and so far it's holding. Other than not being impressed with the adhesive they use, it's fantastic. I can now see the powder level (4.5gr Unique) inside .38 Special cases, which I could not see before.
