i recently bought one for a new pair of leica 3200.com's i am very happy with them we will see down the road how well they stand up. i wanted some thing that i could leave on and would still fit in my alaska guide pack they filled the bill. as i said we will see how they hold up down the road so far i am more than happy. it locks up tight and their is no movement in the connection. as far as this i can highly recommend them.
