I tried it once because i had to go out of town so these comments are based on using once i was going to wait and use it a few times before i made any comments however since somebody asked here goes my opinion after a ONE TIME USE.
I see the advantage with the larger canister especially for additional powder capacity such as the 338 Lapuas etc, it is a bit top heavy when filled all the way with powder. The quality of the hopper is excellent similar to a Dillion. However to change to another powder on a autotrickler set up is problematic since a few grains tend to stay in the bottom of the hopper unable to empty the hopper completely, the Lee hopper seems easier due to the pitch angle and the bottom of the hopper. Keep in mind this is a problem with the autotricker set up only where the Lee base is screwed onto the upper cover of the scale. I'm going to continue to use it because i do want it to work, its a great addition if i can figure to drain all the powder out easier without spillage. I am located in Miami where humidity is high so i do not leave powder in my hopper, I empty every time after use.When the Hopper is removed there is a opening at the bottom of the Hopper so the left over powder can spill out.
