I bought my AZ4 10 years ago for use with what ended up being a variety of fl 6.5/7/7.5 refractors, I love em. What I don’t love is the thought of a grands worth of telescope pointing at the zenith being held by a single bolt. This simple up grade not only adds security, it also really looks good too and adds a certain quality. I have added two hex bolts where the moveable handle was permanently so it’s held very securely indeed. Lovely quality like all ADM products. Highly recommendable

Perfect seller speed and good price 👍🏻
